I know this question has probally been posted before but here goes. I have 5 8week old isa brown pullets and 2 7 week old blue or black silkies there is quit a size difference, can I put the two together now before the are older or will the isa browns hurt my silkies. I have my other silkie in with my big girls and they never hurt her. But she was bigger then them when I got her. They are in a seperate pen. I hate having 3 seperate places. My DH built the young ones there own coop and we are dividing the run. So what should I do?
