Ok so as of right now I have 8 Isa Brown hens, they are about 21-22 weeks old. I'm looking to pick up some 10 week old chick(ens) from a farm just outside of my town. Not sure of the breed though just yet. But my question is can I put them in the same coop as my other chickens or would I have to put them in something else for the time being? I'm only looking to pick up about 2-5 more.
