We had 4 polish, 2 turned into roos so we traded them for 2 younger pullets, 1 -BR 1- GC they have been in solitary for 1 month now they are 8 weeks old . for the last 2 weeks they have been in a portable pen next to the pen with our 2 polish pullets in it . the polish are 15 & 16 weeks old. We are worried about putting the 2 younger girls in with them. We are hoping for some advice or any tips that those with more experience, or have done this already have to give. T/Y Mike & Angie So we put them in just a few minutes ago Frow the white crested black who must be dominant has been pecking at them not hard or on the head just on thier backs. She has also been chasing them a little. We are hoping it doesnt get worse than that, this might be smoother than we thought. We hope they will all go in the coop together tonite!!
