I have 25 chicks that are a month old in the house now. They are getting so big and outgrowing their brooder. I may be able to keep them in the house for another week or a bit longer but that will be pushing it. I have 6 young pullets, around 7 mo. of age out their now. It's a big coop. Do you think I should build a area for them or just add them and keep an eye on them. Building a wall would be a lot of work. I'm thinking that since there are so many of them they will be fine but IDK for sure. Just wondering if any of you have done this before. I'm adding heat lamps since its so cold here.
