They are all 2 weeks. She is not able to eat or drink on her own. In fact, today we hadf a dehydration scare. I don't know what to feed her! She may have gotten pecked on the head. She has a high vaulted skull, which may have been why she was affected so severely. She is not seperated from the other chicks. She is in the brooder box, but in her own little clear bin so she could hear them and still get the heat from the heat lamp. So she is with them, just isolated.How old are our chicks ? Sometimes it takes weeks for major improvement. My last one was young.. only 3 weeks I think when she developed wry neck. It looked awful but she was always able to eat and drink on her own. Every time I was would approach she would go into the tucked head odd walk thing. This pretty much happened for the whole two weeks and suddenly she was like normal. It didnt ever happen again. I think she may have been bonked on the head by a bigger chick ? I left mine with some mild mannered chicks so she wasnt stressed by being alone.
