So I am considering getting 4 black austrolorps supposedly they just started laying. I am just concerned about mixing them with my birds. Currently I have a 20x10 dog kennel with a 4x6 coop attached to one end. My newest chickens, now 2, never slept in coop, but on roosts in the covered/tarped corner of the kennel. Only the rooster and his sister, almost 4 now, sleep in the coop. I guess my question is... how should I go about acclimating them? I can add another 10x10 kennel and make an L out of them... I worry that if I just put them in, they will be harassed mercilessly, some of my chickens aren't too nice to each other. (I currently have 6 hens and 1 roo.)
