My peahen is 9 months old & lives in a run/coop with my chickens. The coop is a converted shed with multiple levels of roosts. All my chickens sleep on a roost but my peahen prefers to sleep on the floor...she use to roost but maybe the past month or so she seems to prefer the floor...at bed time i put her on a roost but within minutes she hops down....I've watched & no one is bullying her...why is she doing this? Is it ok to just let her sleep on the coop floor or should i keep trying to put her up on a roost?
