Howdy all. We have a small group of quails and are pretty new to chick raising. Lately, I've noticed one has a severely swollen foot that has only gotten worse, and her back toe is shriveled and black. Her feathers are fluffed up and messy, and she's not as skittish as her siblings. I've checked the foot, and can't see anything that could be cutting off blood flow. Is there anything I can do to help her?
