I purchase a few day-old chicks to be raised by my 2 broody hens about 2 weeks ago. The chick in question is a Buckeye breed, aprox 2 weeks old, Yesterday I noticed that when she was walking around she had her neck/head twisted/turned to the side, as if she was looking up with one eye and down with the other. The other hens and chicks all appear fine. I did watch her drink and eat today. She is growing a little more slowly than the other chicks. They free range in the yard. Last weekend. She's the chick with the darker head, all the way to the right, and seemed fine to me at that time: I looked at the links for diagnosing disease, and it's hard to say what might be. I just went out to check on things. This is the first night the hens have gotten the chicks to go up into the loft, all except her, she was hiding down below, and so I picked her up and brought her in for a few photos. I think she passed some watery stool onto the paper towel I rested her on. After a few photos she took flight and flew off the counter. I put her back out with the rest. She was peeping loudly, but settled in under "mom" just fine. Now since I am pretty sure she has watery stool, it gives another clue in the diagnosis. I am thinking now that I should have isolated her. It is very difficult to access the area where they sleep, and mother hen is not very friendly at this point in time, so I'm not even sure I can get to her. Does anyone have any ideas, I'm getting worried.
