missing feathers

I am having an issue with my chickens missing butt and tail feathers and some have very red butts. I have treated the whole coop with permethrin and DE. Please help!

So I have a 7 week old leghorn that has some issues. First, she is about 3x the size of my other leghorn and is wobbly and not walking right. Also, for like 3 weeks or so she has been missing a bunch of feathers. Her entire underside looks naked and under her wings. About a week ago she was in a...

We purchased the two as chicks. They are now 9 weeks old or close to it. Not sure what breed. But something like California giant? These two are kind of seditary, who wxot the coop and just lay there. They also seem to walk lame. My biggest concern in the missing feathers and exposed skin rhat...

Hello, everyone! I have fourteen standard hens, all assorted breeds. A couple weeks ago, I noticed their feathers in the bottom area of the back were plucked out, and the pink flesh was showing. I assumed my rooster was the problem, and removed him immediately, even though fourteen hens for one...

My chicks are about 3 weeks old and I've had them for two weeks. I just noticed today that most of them have what appears to be peck marks on their backs! Feathers are missing, and some are even bleeding! What is going on and why?? - It's the same spot on all of them. - Some have it worse than...

Can anyone help me identify the root cause of my bare chicken butts. Although I imagine I would not see lice or mites given their size, I have put down food grade diatomaceous earth. It is only hens and not all of them. Rooster show no signs, nor do any of the young chicks we recently put out...

These guys grew up together. They have together survived 2 fox attacks. They have been fighting each other for a while. They are half soaked and covered in mud, which makes me think they fell into the dam? They have this mad look in their eyes, and they had blood all over them. They were both...

I have a 8 month old white crested blue polish rooster, in August as he was molting I noticed the feathers on the back of his head had been plucked out. I first though he got into a fight with one of our leghorns since they are very moody birds. So I took him out and isolated him from the rest...

My Wilma is missing several feathers from her head.. Does anyone seem to have any ideas as to what has happened? She wasn't missing any feathers yesterday, we had an issue with rats getting in their coop a few weeks ago (but we believe that to be remedied), she started laying eggs about 4-6...

Hi guys! So I've had four two-year-old chickens for about two weeks now and just have some general questions about their looks/behaviors. All four are red sex-link hens. Okay, so the first thing I've noticed/questions is some missing feathers on only one hen's lower neck/upper breast region...
