We let our 2 new silkies in the run with our 30+ week old and two 10 week olds. Our new one's are 20+/- weeks old. In the run, I gave them all apples and some melon to munch on. The 10 week olds chased the new one's around the run constantly, pecking and jumping. I figured they'd cause no harm so small. My oldest stood in the middle and just 'watched'. Finally there was some calm and everyone just ate up until sunset. Then the little one's ran in the coop and my oldest "Muppet" stood at the entry and won't let them in. No pecking, just low bucking sounds to show she was serious. Then one of the newbies took a peck at her and she just went like RAMBO CHICKEN on her! Got her by the neck and held her down. I had to pull her off. No blood but a beak full of feathers. She opened her mouth and let me pick them out, and then went calmly back into the coop and curled up in the corner. Our new additions are just laying in front of the door (were laying). Now my husband says, they're just letting each other know who's boss and to just leave them be to work it out. Apparently, shortly ago my husband said the newbies (no names yet!) have sneaked there way past the guard. I'm afraid that in the middle of the night there will be a blood bath. Should I just leave them be like he says? Listen for awhile and make sure everyone is out cold for the night for real? Or should I just go in and move them back to their pen? I want them all to be comfortable with each other, but that last fight made me really uneasy!?
