My chicks are 5 days old. I had not noticed until a few minutes ago that one of the chicks foot has turned in. Is that straddle leg? They have good bedding, nothing that would make her go straddle unless it just happens sometimes. Everyone is thriving including the chick with the bad foot. I just noticed what a hard time she is having walking, and is hopping on her good foot. She can't get around nearly at all now. It does't look broken, just turned. Do I have to put her down? If so.. how do you do that humanely?
