One week ago, we had 6 showgirl chicks hatch. They eggs were hatched under our Brahma Bantam hens, who are quite broody and just the best mothers. In addition to the showgirls, we hatched 15 assorted bantams and 3 silkies. All the chicks have been doing well with their various momma hens. Today when I went to the hen house, one of the Showgirl chicks was laying on the floor with its head down. It was alive, but clearly lethargic and its right eye did not look right...almost closed. I brought it in away from the other chicks and gave it electrolytes, vitamins and a little applesauce mixed with its medicated chick feed. It perked up for a little bit, but then began laying with its head down again. The chick has been on medicated chick starter and has been eating/pooping normally. The weather is extremely hot, but the chicken house is very well insulated, has a window fan to circulate the air, and is quite comfortable even in this heat. Until this morning, this little chick looked absolutely fine. All of the other chicks appear to be well. I am new to little chicks and am at a loss as to what this could be and what to do for it. We love our pet chickens, and it is so sad to watch this little guy lying around like this; if someone could tell me anything I should be looking for or doing, I would so appreciate the advice. Thank you in advance for any help.
