Today I brought home a BA approximately 10 weeks old. She's underweight and her feathers are in bad shape--very ratty. She's dirty, lethargic and smells terrible. Any suggestions on caring for her? She came from a small hatchery/farm where she had been in a brooder with approximately 20 other chicks and didn't get enough to eat (and obviously picked on terribly). Any suggestions for caring for her and integrating her into my existing flock of four 7-week old chicks? Thank you!
