One of our chicks can't walk very well. We noticed it around 5-7 days ago and seems to be declining. At first it looked like one leg, but now it looks like both. She kinda walks like a penguin and both legs seem to go outward. She isn't walking much anymore, she will take a few steps, but then sits down, and she sits to eat. Please help! It's my 7 yr old daughter's chicken and she is so sad. Thanks!
