All of my chickens were raised together from day old. They get along fine. 15 of them. I always wanted a couple barred rocks so I got 2 last weekend at Lucasville poultry swap. They are 5 week old pullets. I put them in the coop and the flock completely rejected them, they won't let them out of the corner of the coop. I thought it was just going to last a couple days but it has been 8 days. I have a beautiful rooster. When the barred go to eat food he attacks them and pecks their backs hard. They return to the corner. Anything I can do to speed up this process? Don't want them to starve to death. The coop size is no issue. They have 100 sq ft inside, 125 sq ft outside in the run. Total 225 sq ft. I open the run in the evening for them to free run but I can't now because the barred rocks would run off no doubt. Thanks.
