Ever since my new chicks, now 7 wks old, were released into the coop my 2 yr olds hens have stopped laying in the coop. Everyone gets along pretty well. The chicks insist on using the same roosting bar, even though I put a lower one for them. Only the white leghorn pecks at them, but they curl up with my Silkie, who doesn't seem to mind, at the opposite end of the pole. My hens are now laying under a bush up on a hill in the yard.UUHGG! I tried locking them in the run, but I have one chicken that gets so noisy I can't stand it so I let them out. I have put some fake eggs in their nesting boxes, I don't know what else to do.
