My flock is small, with just 2 laying hens, 1 rooster, and then a broody with 19 chicks. The broody and chicks sleep on the floor of the coop. The rooster and 1 hen on the roost, but the other laying hen is always looking for somewhere to lay and sleep, but won't use the floor. I have had to net off all possible areas for her to lay-roost. The nesting box is small, but I see her eyeing it at night, when it is time to go to sleep. Why would a hen hate to roost?
