Hello eveyone. I'm trying to help my neighbor who added a year old polish crested mix roo to her flock of twelve, eight month old production red pullets two days ago. She put him on the roost with the others the night she brought him home. Several pullets fought him a bit the next morning but then they all settled down. They all stay together during the day (free range), one pullet stays close to him and he is trying to mate several of them. Everything is fine during the day but he will not go into the coop at night to roost. He flies to the greenhouse roof then flies onto tree branches and spends the night there. She has tried to entice him into the coop with treats, tried to catch him but he flies away. Does anyone have suggestions on what she can do? Thanks
