I have a yr old hen and just within the last few weeks, she refuses to go to roost. She used to be the one that would dominate the perch, but now, she won't even get on the perch. she is in the coop , but on the floor. I have been going in nightly and manually putting her on the roost. is there any 'rule' or advisement of just letting her be? Let her sleep on the floor? She is not ' under' the other birds and is not in danger of getting pooped on. they are locked up tight at night, so a predator issue has not been an issue. Can I let her sleep where she wants? She is my fav hen. I do not understand why she would change after a year of roosting.
