I've read a few, actually a lot, of posts that are completely against keeping chicks with older chickens. I raised Beatrice, along with two roosters I had to give away, from the moment she was a week old and I've had her ever since. She's now 23/24 weeks old and lives with two Black Australorps called Elsa and Beyonce, whom are 14 weeks old. Now, I'm not gonna lie, we had our problems at first but once the young blackies figured out Beatrice was in charge, they've grown very close and once, when I suspected she might have mites, and they wouldn't stop chirping until I put her back- mite free, might I add. They've been with her since almost 3 and a half weeks old and we've never had any issues. Beatrice is very gentle, snuggly and especially kind to strangers of the chicken kind. I'm glad it worked out so well. This is just a post to share my experiences, not in any way to go against what people said. Beatrice is a lovely chicken and nice natured, I'm pleased to of had her while going through my first chicken-keeping experiences. Thanks, Rachel.
