I bought a chick a few days ago. She is just fully feathered out.. had her in a brooder with 2 other chicks. One was a 2 month old, well no.fighting has went on but I believe the bigger one sat on the chick and broke its leg.. shes really tired and holds up her leg, sometimes she.will let it sit to keep balance or paw out a few times.. i put Sav a chick in with their water.. Anythinf else I.can do?
