HI, We are new parents of 5 little chicks. We have had them four days. This afternoon I noticed that one of the little girls is favoring her leg, not knowing what else to do I have separated her from the others in a cardboard box with food and water within the brooder. She has eaten and has pooped. She seems healthy...she is actually chirping quite a bit and is looking for her little sisters. Anything else I should do???
