Once my chicks get out of the brooder, can I put them with my older hens? I have a dog kennel that is 12 by 7 that they can go in temporarily. My hen house is 10.5 by 7.5 feet and the run is 34 by 16 but it slants so it isn't a square. I have 14 hens and 1 rooster in the coop now. I have 31 chicks. They only need a place until they are 4 months old when I rehome them. Do they not need as much space as an adult bird at that age? Thanks for the help!
