When you come to the hard decision to euthanize one or more members of your flock there are many ways to do so. If you aren't able or willing to eat the bird then your options increase. If you are like us, you read as many posts as possible and decided that cutting or shooting and the subsequent bloody mess are not in your skill set; consider using engine starting fluid (diethyl ether) as a humane way to do it.
Though we read many posts that described the steps - sort of. Last night we had to do it for the first time ourselves and we documented as much of the process as a way to help others with this and understand that it's possible. Below is the list of supplies, steps and we explain the variables that may change for your specific circumstances.
Plan for this to take 30 minutes at minimum.

What happens:
The ether and C02 will put the bird to sleep within 30 sec. to a minute (we heard a soft thump as she passed out) and then within a few minutes (5 minutes in our case) the bird will die from the fumes. There will be convulsions for 15 to 30 seconds as they pass, its normal and they cannot feel it as they are asleep. That is it. I did it mostly on my own, it was my turn since my partner had another chicken die in his arms while I was away at a conference.

Location/safety:
- Do this OUTSIDE, a must and away from family and other animals - diethyl ether is toxic and very flammable - stay away from flames, sparks, etc.
- Know how you are going to dispose of the body (bury, burn, necropsy examination first) and have that prepped before starting.

Timing: night so your birds are roosting and more docile, including the unfortunate subject

Supplies: required
1 can engine starting fluid (available at Walmart or any auto supply store): Amount will vary depending on size of bird (for a 4.5 lb pullet we used about 1/3 of an 11oz can)
Air filtering mask - 1 for each person involved (we used paint masks from a home improvement store - they were ok but I got a headache from the gasses)
1 5-gallon plastic bucket with solid lid (clean - because, come on, its the last place they will remember)
1 garbage bag big enough to cover the bucket
4 to 5 paper towels - or old wash cloth - plan on throwing out after use
headlamp or flashlight
old towel (tea towel size or as large needed to hold the chicken)
chair, bench, someplace to sit
Optional:
line the bottom of the bucket with some bedding material or an old towel
rubber gloves - thin surgical style gloves
Brick

Steps: after dark
Bring all supplies outside and set within reach of the chair
Turn on flashlight or headlamp
Set up the bucket (with towel or bedding if wanted)
Practice sealing the bucket - Lay the unopened bag over the bucket and cover the bucket making sure the bag isn't preventing a good seal - Set aside so you can reach it easily
Put on mask(s) and gloves making sure the mask fits tight
Hold towel(s) inside the bucket - spray towel(s) with enough fluid to wet the towel(s) really well.
Leave in bucket and close lid very tightly (place brick on top to help seal)
Wait 1-2 minutes before fetching the chicken (allows fumes to saturate bucket)
Get chicken from coop (make sure to close the coop if she wasn't isolated already)
If you want to wrap her tightly in a towel (we did not)
Open lid, place her in quickly, reclose lid with plastic sealing lid. Check lid to make sure its sealed, weigh with the brick.

Have a seat, this is where patience is important
Listen quietly for a light thump.
Wait for the convulsions to occur, it will sound like nothing inside until the body starts thumping inside the container for 30 secs to 1 minute after a 5 minute wait. (we picked up supplies while waiting, but was done within 3 minutes) It also got us away from the fumes.
We waited another 2 minutes to ensure it was over.
Check your masks to ensure the seal is good, still be careful of breathing too deeply.
Take off lid and check the bird, its likely to look quite disheveled, probably with fluid around mouth and if its eaten expect droppings.

I used the garbage bag to hold our bird while taking the contents of our 5-gallon bucket to the trash dumpster. Don't leave the fluid soaked towels, etc. around dangerous and flammable stuff, seal in a ziplock if throwing away inside but I do not recommend it.

Other considerations
I've read that older birds can take longer to succumb. Research this please.
Check the weight of your bird, ours was a 6 month old pullet 4.5lb (1st egg killed her), we probably overdosed a bit but at $4 a can it was reasonable to use 1/3 to 1/2 the can.
Practice safety, please do not breathe the fluid directly.

I performed a necropsy (not covered here) then buried the body in the back yard that evening in the hole I prepped earlier that day. The takeaway was she had ripped her oviduct and had an egg floating in her abdomen, a death penalty that would have been painful for her.

No matter what you believe, know this; it's better to end pain for an injured or sick bird soon and humanely.
 
I am mentioning the following in the interest of continuing educational info on this topic. I am not judging anyone as this is a very personal and difficult decision for each of us and everyone must decide their own way. Suffice it to say, as a clinician, I do not consider this method humane.
You know how your throat catches when you are near those fumes, and your eyes burn if it wafts toward your eyes? Now imagine being immersed in there. Unfortunately, ether is an irritant and all sensitive mucus membranes (eyes, nostrils, throat, lungs) will burn on exposure to a concentrated amount of this substance. It isn't like giving an anesthetic in there. Anesthetics are given with oxygen and in a controlled manner; the patient is not immersed in a chamber of concentrated noxious gas.
Are there worse ways to go, absolutely...but this is not as quick and painless as people may think. It takes a lot of thrashing around in a confined space, long minutes before induction of unconsciousness (compared to other anesthetics, the ethers are relatively slow), fear and pain for the bird in the interim before succumbing to hypoxia...it just doesn't seem like an easy death. In one study, several methods were compared for the euthanasia of chickens, and ether was ruled out as suitable because it takes so long and causes airway irritation. They discontinued the study when the birds were still conscious past 60 seconds. The fact that the bird thrashed around, had fluid coming from the mouth and evacuated her bowels indicate distress prior to collapse. It should also be noted that ether is extremely dangerous. It is highly flammable and a cloud of it will stay concentrated rather than easily disburse, so the risk is prolonged.
I hope this doesn't upset anyone; it is important that we are armed with all the knowledge possible when considering matters as sensitive as this. Again, no judgment; I applaud OP for wanting to do the very best for their poor hen. RIP sweet spirit. You were right to put her down btw and saved her so much pain and suffering due to her ruptured oviduct!
 
I applaud all of you for being willing to discuss this topic, and to consider humane methods. I am new at this and I am struggling trying to think how I would do this if necessary. I consider myself a responsible pet owner, and realize there will come a time when I wii do this, but how?
I am also a clinician and was concerned about the method just discussed. I know everyone means well, so no judgement, but can you suggest any other methods?
 
We all do things differently and have our own opinions. Putting any animal down should be done as quickly and as painless as possible.
I do agree with the other posters, CO2 is not something I would consider using, but again, no judgment. There are a lot of discussions here on BYC about different methods, the pros/cons. No one way is perfect.

The best each of us can do is research and find what we feel is best for the bird. I realize putting a bird down, especially if a pet, can be very difficult and emotional, but we have to remember to put them before us in this situation.

For me, I use the "broomstick method" (cervical dislocation). If done correctly, there is usually no blood and the bird dies quickly.

For very young chicks, decapitation with a knife, for me is the quickest.

I do hope this discussion will continue to be both educational/informative and help others looking for help with this difficult, but necessary part of keeping chickens.

I want to request when you state your preferred method to be very different then you DO the right thing and share a detailed description or make a video with details about your method. Make a difference where you disagree, a mentioned study does not contribute in a meaningful way.
I spent the better part of 3 sleepless nights researching this topic and found little to no detail on 'properly done broomstick' and quite a few horror stories about failed jugular cuts and complicated car fume mishaps. We are in an urban situation so guns are not an option.

I am encouraged that I was able to piece this method together from hints that other posts included but without visual or descriptive back up. Simple and direct, while considering safety.

I want to remind readers we had indications that the pullet passed out after about 30 seconds so the convulsuions and any irritation was after she was unconscious. Under 'normal' death most creatures lose their proverbial $hit. It was nearly 100 degrees that day so I'm not surprised that the pullet had excess water/fluid in her system and convulsions pushed it out after passing out. If you don't understand - chickens drink heavily just before dark and roosting in hot weather and we did the euthanasia shortly after dark so her digestive system was pretty full of liquid still.

Again it's a personal choice, but lacking the detail that makes it repeatable by us we felt other options were not good choices.

Thanks everyone for the posts about your preferences, the passive judgement where clearly implied and most importantly the support where it was honest.

Some background, we did take her to a very expensive avian specialist because she was a rare specialty breed given to us by a friend when we noticed her vent was inflamed. They were great and very encouraging. BUT They wanted thousands, literally, to do surgery to remove the egg, give her meds that meant we'd never be able to eat her eggs even if she survived the anesthesia, and surgery, and laid again. We did get calcium and anti inflammatory meds to help her possibly pass the egg naturally and without pain if possible if she could.
Inspection didn't determine what was wrong, we didn't pay for xrays, that would have ultimately said it was an egg. Duh, I too could feel it from exams.
She simply was dying and couldn't do what a chicken is meant to do. We raise productive pets, some of our old girls have stopped laying and they've earned the right to life out their lives with our flock. She earned the right to not die slowly and more painfully than I can imagine. In the necropsy I found some other health issues that make me believe she never had a chance - gory and I won't post details here. She was on bottom of the pecking order for a reason but we treated her short life as a gift.
 
I am sorry if you felt I was criticizing your method, I really only meant that because of what I know, it is not a method I can consider using. You did right by giving your chick a quick death;it’s what we all want, right? Quick and merciful. As with everything we all have a preferred method, if we can find what works. No finger pointing.
I also agree with you about people posting the directions for how to perform the steps for each method. I still can’t figure out how the broomstick method is done.
The only method that was clear to me is the chicken cone method, but that’s too bloody for me, and what do I do with the blood?
Thank you for your post, I appreciate everyone who takes the time to share information.
 
Again, my post was not meant as a judgment in any way; I felt my post was in the spirit of all of us garnering better knowledge on this topic. As I said, and as this vet says, going about this decision is a very personal and sensitive one and we will all have varying thoughts regarding what is morally, ethically and emotionally the best course of action for us to take given the very unique circumstances of each case. You acted with your hen's welfare in mind and you clearly loved her and did your best for her.

The following is from a veterinarian, regarding humane and inhumane methods for euthanizing backyard birds. I hope it proves helpful. I think the greatest take-home lesson on this topic is the following: Euthanasia is NOT about making the bird dead; it is about rendering them unconscious as quickly and painlessly as possible. After they are unconscious, the method of killing the body is much less important. He outlines, in very specific detail, a couple of methods.

The following is the study I mentioned, in which ether was found to be an unsatisfactory anesthetic due to a too-long time to unconsciousness and due to its irritant nature on the mucus membranes, eliciting distress behaviors, etc.

I'm very sorry if you are offended or feel that judgment was made, this is not the case at all. Each of us face this very real and hard decision at some point in our lives. Like mentioned previously, all of us have to find whatever method is best for each of us.

I will reference some videos below.

If you want step-by-step, I will try the explain what I do: (this is for putting a sick chicken down)
  • Have what you need ready - something sturdy like a broomstick, rake, pole, etc. I use a rake with fiberglass handle, it's heavy and sturdy. Know where you are going to put your chicken down, you need firm ground.
  • Take a few minutes to pet/love and say goodbye to your sick chicken.
  • Set your emotions aside and know that what you are doing is an act of kindness, they are suffering and you need to end it.
  • Lay the chicken on the ground, keeping hold of both legs.
  • Place handle of broom, rake, pole across the base of the skull (back of the head).
  • In almost one motion, step on the rake on either side of the chicken's head and pull back and up. Do this quickly and firmly. Pull harder than you think you will need to. Better to pull harder and the head come off than not (sorry if this sounds bad). There will be a little blood if the head comes off.
  • You can feel and hear the dislocation.
  • Go have yourself a good cry.
  • Perform a necropsy if that's what you plan on doing.
  • Bury your chicken and mark the grave how you see fit.
Now, there will be some flapping of the wings, this is nerves, but you will see that the neck is clearly broken and/or dislocated. If the head comes off, there will still be flapping. There is sometimes saliva/liquid that comes from the beak. Same with feces, there are no muscles engaged to hold any bodily fluids in.

One of the better videos of the "broomstick method" is found at post# 6 https://www.backyardchickens.com/threads/euthanasia-information.1195265/


***Other videos-you may need to sign in to google or youtube to view, even though I have done this a few times, they can still be hard to watch, so viewer beware.

These are more for "harvesting", but methods are same. A sick chicken usually does not put up much fight.
Granted, this is a rabbit. In this video, you can clearly see and hear the disarticulation. The person that performs this method will also feel it. Just replace rabbit with chicken, everything is done the same.

In this one, method is very similar, the jerk is very hard making the head come off - instantaneous death.
 
Does anyone have examples/pictures of mechanical cervical dislocation devices that have been “approved/tested”
And deemed effectively humane to use?

What exactly are you looking for? You can do a google search to see if there is a device that can be purchased.

My "device" is a rake as described in the previous Post
