I am waiting on 10 chicks next week. out of my old flock I'm down to only two three and a half year old hens. Hubby is building a bigger coop so the Hens sleeping arrangements have changed. They are both Silkie hens that grew up together. Penny my smallest hen has been a bit spooked so I peeked into their window tonight after putting them to bed. Penny tried to crawl under peeps bottom!! she didn't fit so peep spread out her wing and penny DID FIT UNDER IT. they both went to sleep that way! Peep is a lot larger bird than penny. Peep is a silkie cross and penny is all silkie. so at night penny a fully grown hen sleeps under her friend peeps wing to feel safe. I thought this strange but very very sweet! Has anyone ever heard of such a behavior??♡♡♡♡ chicken love and friendship, priceless!!!!♡♡
