I am new to raising chicks. Got my girls when they were 3 days old on 4/1/11. They have been so much fun and good layers and no problems till now. One of my barred rocks has stopped eating and drinking. She just sits in the coop and doesn't come into the pen. The only thing that I know has happened to her is she got her leg caught in the chicken wire that's under the roost. Does anyone have any ideas?
