I hatched 24 chicks of mixed breeds and they are now 5 weeks old. I moved them to a large 4 x 6 brooder/ enclosure in my little barn at 4 weeks and every one was doing great. I noticed after a few days that one, looks like a RIR mix, was standing up but it's head was between it's legs. It tried to walk but would do actual flips and then get back to its feet. I had a chick with wry neck once so I thought that was most likely the issue. I brought the chick inside and it's been in for about 4 days. The issue seems slightly better but the behavior seems really odd. I think it is a pullet and she is still standing, backing in to the corner and tucking her head under her to her rear to sleep. She eats and drinks normally but then resumes this odd behavior with her head and also seems to hallucinate. She pecks at her underside like she has mites or something but she doesn't and she looks around her at the ground like she see's things. She also just jumps and flips all over the place at random inside the enclosure. I can rub her feathers and she seems to enjoy it but I have been stumped by her behavior. I've been dosing her with vitamins and of course keeping an eye on her. I am going to keep trying as long as she is eating and drinking but has anyone seen this crazy behavior before?
