We have always had two roost in our enclosed/secure run. The other day the roost fell over. The chickens hid in the coop and would not come out near the fallen roost. No on is injured. we took the roost out of the pen for 48 hrs and put new more stable roost. Well they are walking around them, but not roosting on them. Is their memory that good? I have sat out there with them, put treats on the roost, and even picked them up and placed them on them. will not sit on them. Do I just need to give it time. They used to love to sit up there and warm their toes and groom themselevs. Any suggestions? Thanks V
