Hi, I have 9 hens, 1 rooster, they are just over a year old. I ordered some Easter eggers & buff Orpingtons from a hatchery. One of my year old buff Orpingtons has been broody for over a month, so I gave her the chicks this past Tuesday. She has adopted them and is a good mama. I have them in my coop inside a very large dog kennel. Chicks will be 1week & 2 days old on Today. I am looking for advice on the the best age to let the chicks out into the coop with the mama and allow them to free range and assimilate into the flock. I’ve read after the 1st week, to waiting for several weeks. I can’t imagine leaving them cooped up together in a dog kennel for weeks. Any advice would be greatly appreciated!! Thank you!!
