So I maybe haven't waited enough time, but I have gradually introduced 3 silkie hens into the coop/ run with my 4 ISA brown laying hens, and 2 Cochin x hens. They have now been together for 4 days. The brown hens seem to relentlessly chase and peck at the silkies, some times more than one ganging up on one and pecking and jumping on it. I'm feeling really bad for these poor silkies, they don't even fight back. I'm really hoping they can all get along. The run and coop are definitely large enough for the 9 hens. I have no rooster. Any tips or suggestions would be greatly appreciated. Thank you.
