I just went out to check on my chicks (they are almost 7 weeks old) and one of them seemed to be laying with her right leg in a weird position, it was straight forward underneath her and out to the side a bit and her toes look to be curling in towards each other a little bit. I picked her up and her feet felt a little cool. When I put her down she took a step or two and then laid down. We did get her to walk a little bit, but it looks like she is limping. What can I do for her?? She is my only Blue Wheaten Ameraucana and I REALLY want her to be ok. Please help me!!!!!
