Hi all, we have a sick cochin chick. She is 8 months old. We noticed a change in her behavior 2 days ago. She is very lethargic now and she was too weak to jump on her roost in the coop the past 2 nights. So we took her in to keep her warm and so that she can get some rest. We changed the food (organic chicken layer feed 2 days ago from one brand to another). The pellets are a little different - larger now and the color is different). Poor chick has watery stools (never had before) and drinks a lot. She has never been as active as the rest of the flock but yesterday she barely walked, only very slowly. At least she ate yesterday. Today she would not even eat on her own. I made a mixture of egg yolk, oats, grated apple, some cat food and cottage cheese and she seems to like that and ate half of it. She sleeps on and off during the day now and drinks a lot. Her comb is a little pale too. Do you have any other suggestions on what I can give her so that she gets better? Thanks for your help!
