I have a coop/run that is 15x10...and I free range when the weather's nice on our 1.1 acres. I currently have 2 BR roos and 1 roo which we adopted a couple weeks ago...along with 5 RIRs and 3 hens which we adopted as well....we think the new chickens are Phoenix...they're still growing in their wattles and such. The same person that gave us the Phoenix chickens also has 3 bantams in their own little hutch over in her garage. We plan on adopting them as well, but I was debating on whether I should keep them in their hutch (literally a hutch about 6 feet tall by 3 feet wide), or can I mix them in with my other chickens in the coop? I'd like to be able to let them mix and free range with the others, but I want to do what is in the best interests of the birds, and not just my own convenience. I'm sorry for not knowing the exact breeds of the new birds...but the lady that I'm adopting them from was just getting started in raising chickens....and is a little bit scatter-brained herself. When one of her chickens ran off one day, she reported it to the local PD and couldn't tell them what it looked like other than it had brown feathers. Thanks for the help.
