Hi everyone....I have a problem here i hoped someone could offer some advice on....my wife and i have four production red hens that we've had for about 5-6 weeks. They've been in a chicken tractor up until now. We decided we wanted a few more hens so we built a new stationary coop with a 20' x 35' sized run (we live in town so can't let them free range). We finished it last Saturday, and turned them into it. A little while later we bought two young Black Australorp's, not quite laying yet, and when we introduced them in to the new coop, the red hens pick on them and chase them around. They won't let them into the coop at night to roost. The black's huddled in a corner of the run last night, and we felt sorry for them, so i put a nice big box full of straw and they climbed right in. Winter will be here soon though....is there anything i can do to help these hens accept the new ones? Or will it just take time? We hate the discord in our little flock!!!!
