broken/missing feathers won't regrow

[NewFlockOnTheBlock]

This is Chanterelle, our friendliest Buff Orpington hen. She is missing feathers on her back and on the tops of her wings. The ones on the back are completely gone; on the top of her wings some are missing completely and others appear to be broken off and the shaft stumps have a sort of a jagged edge. She grew a bit of down to cover a small part of the bald patch on her back but as you can see most of it is still bare, with no sign of pin feathers. Also, Chanterelle's tail feathers look very thin, particularly close to the base.

This started as feather loss due to over-mating this past summer but our rooster in not mating with Chanterelle much these days, I'd say maybe once a day at the most.

What do you all think is going on? Could Chanterelle have feather mites or lice? So far I haven't been able to spot any on her but I will bring her inside tonight and will look again with a flashlight and a magnifying glass.

She is not showing any signs of molting although most of our chickens (13 out of 15, with the exception of Chanterelle and one other hen) have already gone through a molt or are molting currently. None of our other chickens have the same feather problems that she does. Our one other hen that had a bare back due our over-zealous rooster regrew the feathers during her molt.

I asked previously in a different thread if we should cover her back with a saddle apron and was told that, in this cold weather, I shouldn't, as it can prevent Chanterelle from being able to fluff up her feathers and protect herself against the cold. I'm thinking I might still try it as the area covered by the apron is almost completely devoid of feathers at the moment, so she should still be able to ruffle all of the feathers that she still has, poor girl.

Broken feathers won't regrow unless they are molted out, unfortunately.

Her skin look very red and irritated to me. Ouch. (lighting might be effecting what I am seeing)

I would not allow the rooster mating her at all... I doubt you are watching always and in her condition... even once is too much in MY opinion.

It's true saddles can cause issues, including more irritation to pin feathers and trouble regulating body temp both too warm or cold. I see you are in Washington... how cold are you getting at night?

It's hard for me to say if there may be mite issues or not with the other known damage. I might treat with pour on Ivermectin ( also treats some worms, egg withdrawal required, and not sure if it's one that shouldn't be used when feathers are growing in) or a permethrin based spray (no withdrawal required, treats most surface pests). I live in the PNW, and most winters have to treat for lice due to abundant wild life. I have also seen mites int he past... but some are microscopic and other only come out to feed while not living on the animal.

I might try the apron also. Especially if I wasn't gonna separate that boy. I would say pay attention to the hen.. like middle of the night, check if she is shivering.

Also, would ask what are you feeding including treats and supplements?

Feathers are made from 90% protein and its' amino acids. So when feather growth is an issue adding in some high quality protein can help.

All right, picked up some pour-on ivermectin today and treated our girl. Keeping her inside tonight for observation. If she handles the dosage OK, I will probably treat the entire flock as they are all scratching quite a bit, even though no one shows the kind of feather damage that she has.

Re: my friend's source to back up the use of injectable ivermectin in water, I'm not sure... I do know that he has studied Gail Damerow's Chicken Health Handbook (which I've borrowed from him in the past but do not currently have a copy of). He also owns several more general-purpose books on raising chickens, and researches stuff online, including this forum.

In other news, sent off some of our flock's collective poop in to the state lab for testing this morning, woohoo! Looking forward to finding out the results, hopefully in the next week or so.

Well you definitely have mating damage which will not repair until she moults but I also see what appears to be depluming mite damage where the feathers have a frayed appearance and that would need to be treated systemically with Ivermectin. Permethrin spray or dust will not get them.

A couple of my buff Orpingtons have also been a favorite of the roosters probably because up to about a week or two ago they were still laying. They have suddenly began to grow back their feathers in the past week. Both look like porcupines currently. Your hen should still grow them back here within the next month from my experiences with late molters.

Have you removed that rooster? At least temporarily? Orpingtons can have a looser feather structure so I wouldn't necessarily think mites.

I also see what appears to be depluming mite damage

I have not seen depluming mites before... . I did fear it once... after a hen got into my stag pen and suffered mating damage which looked bad for a while... vet conformed it wasn't THAT time.

I agreed Ivermectin would treat those, and scaly leg mite... both which are considered not effected by the permethrin products.. as stated they are systemic feeders. However sulfur is considered effective against both as well.

The irritated skin... seems telling though.. While red could be effected by cold temps... most bare ones I see aren't that bad.

I honestly don't know the efficacy of using the injectible in the water source.

YES... I know the havoc that can be caused by a flock members' removal! I have considered using a tie out... not for cock fighting but to keep boys with the ladies but only accessed by the ladies choice.

I'm not sure that Ivermectin can be used effectively in their drinking water. I've not heard of it being administered that way. Were you using it as a wormer or did you suspect mites then?
Pour on ivermectin might be the best option. It is absorbed through the skin and treats the bird systemically.

 

[rebrascora]

You do not want to spray them. The pour on ivermectin is applied with a dropper directly onto the skin by parting the feathers at the back of the neck and only a few drops are required. I would just treat Chantarelle. If you know a cattle farmer they might let you have a tiny amount or the alternative would be to buy an Ivermectin horse wormer and give it orally as a paste directly into the beak. @casportpony can perhaps help with dosage as she is good with medications and calculating the correct amount. She will also know whether the injectable ivermectin will work if administered in the water. It is not the best wormer for chickens and using it regularly can lead to resistance. It may be that you do not have a problem with worms in your climate, rather than that the ivermectin has been effective. I have not wormed my chickens for 5 years and not had a problem with worms. Some people have to worm several times a year to keep on top of internal parasites, so it can vary significantly from place to place.

 

[rebrascora]

No, it needs to make contact with the skin and you need to pull the feathers forward to expose the skin for application. The chemical is absorbed through the skin into the blood stream and then distributed throughout the body in order to kill the mites all over the chicken. Putting it on a few feathers will not achieve anything.

There's a lady here on BYC that makes her own saddles and sells them, you can order one for her..... but I forgot her name, a quick search will probably find do though.
