Um, so I have 7 week olds in the coop. They have a seperate pen from the adults, but they can see each other...the chicks have a seperate fenced run, and the adults free-range. My issue is, My brooder is wuickly becoming too small for my growing 1-2 week olds...and I dont have another pen for them! Can I mix them in with the 7 week olds or can I put the 7 week olds with the adults? I dont know what to do! We can really put up a whole nother building right now, DH is farming and has no time for helping me... what should I do!?
