My three girls are full-sized and free-range during the day. I currently own this Barn. At night, two would squeeze in the nesting box to sleep rather than perch on the flimsy roost provided which is too low to the ground anyways. I decided to upgrade this barn to jumbo size. I modified the roosting bars and blocked out the nesting boxes to get all the girls to perch at night. Fingers crossed! I also received a cracked panel upon inspection that was promptly replaced after notifying the proper group. Good service, decent product.
