I have an EE chick a little over 2 months old that was fine yesterday morning but by late evening was huddled in the corner of their fenced in yard. Her feathers are all fluffed out and she seems to list to the left when she tries to move. Her stools are normal range and she pecks at her food and water a little bit but just doesnt seem interested in moving about like the other chicks. She just sits and dozes unless I jostle her around.All the same age. I am in Southern Illinois, so weather has been a bit wet, humid lately. We are not having trouble with gnats like others have been. I have brought her in the house because the others were tromping her down. I have given her medicated crumbles and have put sugar water in the box with her. Any ideas? Could the nearby mulberry tree be the cause? It hasn't bothered any of the older chickens before. The other chicks seem well today?
