Hi everyone! We are a family of seven who have recently started raising chickens. We have four- a brahma, a bantam brahma, and two wyandottes - who we've raised from 2 week old chicks. They are now about 24 weeks old. We had no idea the one brahma was a bantam and were so concerned about her because she wasn't growing like the rest of them. We're assuming she's a bantam. She is only half the size of the other three. She's always been the quietest, lethargic, and is constantly getting picked on, especially by the other brahma. How can we help her? Could she be sick? Should we separate her from the other three? We could put her in her own space, but were told that chickens don't like to be separated from one another. Thank you so much for any help you can provide. We have no idea what we're doing here.
