Congrats, and I agree with the guesses!
I think one of my adult chickens may have wry neck. I haven't found any really good articles on attempting to treat this. One article said that you can treat them with terramycian, but a different one said to just use polyvisol baby viatmins (without iron). Thoughts? I have used the baby viatmins before, but not for something like this
Thats what I have heard also. I had one that survived to be about 8 months, but it was a severe case.
