I’ll start by answering those questions that are generally required for more knowledge of my situation, following by a curious further explanation of what’s going on.

1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.)
- black jersey giant, just under a year. EXTREMELY underweight.
2) What is the behavior, exactly.
Was eating and drinking fine until yesterday. Depressed. Lethargic, and now is unable to stand.
3) How long has the bird been exhibiting symptoms?
- I noticed something was off about a week ago and it has only gotten so much worse.
4) Are other birds exhibiting the same symptoms?
- No, however, her sister died of very similar symptoms in June.
5) Is there any bleeding, injury, broken bones or other sign of trauma.
- no
6) What happened, if anything that you know of, that may have caused the situation.
- none
7) What has the bird been eating and drinking, if at all.
- I’ve been giving her eggs, and all sorts of higher protein treats and feed. She was eating and drinking fine until yesterday.
8) How does the poop look? Normal? Bloody? Runny? etc.
- Runny, almost purely water (partly due to the fact that she was drinking EXCESSIVE amounts of water for about 3 days). Greenish, sometimes yellowish.
9) What has been the treatment you have administered so far?
- I did a corid treatment due to seeingn some bubbly frothy poop earlier in the week and gave her 1cc of duramycin for four days.
10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet?
- treatment really isn’t an option now. My vet is booked until Monday and she won’t make it. I can not afford an emergency vet.
11) If you have a picture of the wound or condition, please post it. It may help.
- ok
12) Describe the housing/bedding in use

- large coop, pine shavings.


This is why I think I’m dealing with Mereks. Her comb is darkened. She has a classic wing under her pose with one leg stretched out. Greenish / eatery diarrhea and extreme weight loss. Her sister (whom they were both gotten from the same Hatchery exhibited similar symptoms. We culled her after a week. This bird seems like it’s going to die today. She won’t open her eyes or move at all. If I try to balance or stand her up, she falls over. She has discharge now coming from her nose. Clear / watery. No rattling or wheezing. Very lethargic and no longer eating or drinking. Her sister, however did not experience quite the same paralysis and just seemed extremely weak, underweight, poor condition and growth. None of my other birds have any symptoms.
I practice good husbandry, I clean out my coop daily, rake drippings in the yard, etc.

I’ve read online to purchase oxine asnit is a good disinfectant to use. Thoughts on this?

I guess I sort of just would like some input. I am going to ask my vet if he can do a necropsy for me.
I’m aware if it is mereks that my entire flock has been exposed and I need advice for the best measures to take.

She is now separated, in my tub with towels surrounding her because it’s very cold outside. She is very unresponsive at this point and does not open her eyes. I’ve tried to leave her be in the quiet. If she has not passed by tomorrow, we will cull.
I’m going to include some pictures from a few days ago and now. I’m not interested in forms of treatment, I’m interested in knowing best practice if this is indeed mereks I’m dealing with going forward and basically just the best ways to keep up good immunity in my remaining flock.

Thanks for taking the time to read this.
 
Honestly... not sure it sounds like Marek's really... And so many things can look the same. But I know each individual can present differently. :hmm

7) What has the bird been eating and drinking, if at all.
- I’ve been giving her eggs, and all sorts of higher protein treats and feed. She was eating and drinking fine until yesterday.
What is her regular feed and treats including supplements? Do all your "higher protein" treats have as much fat in them as eggs? That can cause diarrhea... as can too much protein actually. As well as worms and liver issues.

Have you ever had a fecal float done to check for worms? Looks like she may have some external parasites... per her feather quality. Some types don't live on the birds but just come out to feed. What does her vent look like? I would treat with a permethrin based spray.

Why administer duramyicin?

Where are you located? Please put that in your profile so others can see at a glance.

For future reference... frothy poop is NOT an indicator of Coccidiosis.

Have you monitored over night crop function? Dehydration is deadly fast... so I would administer fluids of she isn't drinking. But was she drinking when you administered the Corid?

My suggestion would be a few drops of poultry nutri drench straight to the beak. When was the last time she laid an egg?

Sorry for your other loss, and that this gal isn't well. :(

If you aren't in the US then my following links to help with necropsy may not be as useful...

Hope she pulls through and if not, then I hope you at least get some answers. :fl

External parasites do not make sense. None of my other birds look this bad. I’ve checked the coop and everyone over.

My other birds are beautiful, with no issues at all.

Right now everyone is on flock raiser.
Protein treats have just been eggs and mealworms.
Her last egg was about two weeks ago. I thought she was beginning to go into moult along with the others. All of my other birds are moulting. I’ve done nutridrench.

I treat with corid as a preventative anyways every six months or so. I’ve always been lead to believe extremely bubbly poop typically means cocciodosis.
Her crop has appeared to be completely flat for two days.
She’s been drinking until today. So yes, during the course of corid treatment. I did duramycin because I originally thought she was coming down with something respiratory.

I’m just doing what I can with the means that I have.
Her decal float test determined no internal parasites. That was done a week ago when all this started being obvious to me
 
External parasites do not make sense. None of my other birds look this bad.
In back yard flocks it has been shown... 10% of the birds carry 90% of the parasites... as each has their own immune system, dirt bathing habits and such.

Just spinning ideas to look into... We are all doing our best, :cool: hang in there! :fl
 
Additionally I might add that I doused the coop in permethrin spray day the birds a week go on on set.


I’ve been giving her water nd nutridrench but it just lets out of her beak

That’s very interesting!!! I’ve looked her all over. I don’t see anything. And I inspected the coop for mites and found nothing either. I also totally sanitized it last week. I’m just so confused and frustrated and it is ODD that her sister died from much of the same symptoms
 
Some more annoying additional info - the discharge coming from her nose is obviously kind of snotty. I don’t have much else to go on.

To be clear... I'm not trying to say that is your issue at all, just sharing the information so you have it to consider. ALL things.. will attack the weak first.

Did the other gal have snot and lethargy as well?

Snot, lethargy, and not eating... are things I haven't seen in Marek's. They are often very bright eyed and eager to eat.

I am suspecting something more respiratory... but very inexperienced in that area...

@Wyorp Rock @rebrascora @Eggcessive anything to offer here?

Permethrin is effective. :thumbsup

Not sure if part of the sentence is missing or I can't make it out... did you get the birds also?

So cool that you had a float done before just treating. :highfive:

Hoping!
 
It could still be coccidia load...i would recommend you stop treating every 6 months because if they don't have an overload you are actually reducing their resistance to it...normally most chickens carry it in their gut naturally and they build up a resistance to the cocci to remain healthy it is in times of stress or prolonged wet weather that they can succumb to it she may have been stressed going into molt and her system could not handle it please sweety stop with the bi-annual treatments you could be creating a ticking time bomb. Im also very sorry for your 2 girls hopefully a necropsy will shed some light:hugs
