I'm fairly new to raising chickens with a flock of 14. The first set of eggs that I hatched are now 24 weeks and are absolutely my babies. I have two buff roosters named Bach and Beethoven. Bach is experiencing symptoms similar to wry neck. He will keep his head between his legs, loses his balance often, and has trouble fluttering off higher places. He started this just recently. I've been giving him Vit E oil for the last few days. My question is, is it possible for him to all of a sudden show signs of wry neck at 24 weeks? Or could this be something else? He eats and drinks fine, no problems with poop that I've seen. It's not constant, he runs and plays with his brother. Should I be doing something else for him? How would I know if it was a brain injury?
