I have a buff who's been broody three times since late fall, so I gave in and got her some babies yesterday. She took them almost immediately and seems to be doing a great job so far! I've sectioned off a part of their coop for her and the chicks. Pic of mom and my set up attached. How long do I keep them penned up and separated? Any other words of wisdom would be helpful too. This is a first for me. Thank you!
