I purchased some new chicks a few weeks ago and I noticed one of them earlier today had his head tucked downward and he frequently bobs it side to side. He's able to eat and drink. I've done some googling and reading and wonder if it could be wry neck but wanted more opinions as he holds his neck downward rather than up. I've separated him and started treating him with a supplement of Vitamin E and Selenium. Any advice or suggestions are greatly appreciated!
