My Jersey Giant hens are not getting the point to roost on the bars in the coop. I have various roost heights. Plenty of roosting space. These are the first JG I have had so I am learning about that breed still. They keep roosting in my nests. I had blocked the nests off for weeks and they still either find a way in the nests or roost on the floor or ramp to the roosts. Are JG roosting style like Silkies are to roosting on the floor?
