Hello bought my chickens from local "breeder" aprox 1 month ago. He had a huge Turkey barn sectioned off in large coops/pens with stair step roosts close to the the ground. My chickens all hens are almost 4 to 5 mo old (4 are older then the other 2). They roost on the ground next to the wire fence or next to the water bucket. I have gone out at night and placed then on the roost inside the laying house and have also put them on the long roost on the fence...yet they still will not get up there by themself. Do I need a different roost?
