I just picked up 15 1-2 day old chicks today and about 30 minutes after putting them in the brooder one chick suddenly decides that she no longer wants to walk and just layed on her side as far as she can from the brood light. I panicked when i picked her up and found that she was pretty cold so i made a quick heater for her (ceramic cup with water put into microwave and cloth around it to keep her from getting burned) and she immediately curled up next to it. But it seems that her toes are starting curl and her legs are getting really stiff and she wont eat and is really lethargic. Does she have some sort of condition or birth defect? Is there something i can do for it? The other chicks are fine it seems its just the one. And this started happening about 5-6+ hours ago. The profile pic is her when it started and the below is just a few minutes ago.
