Hi, my chicks are 6 weeks old now. How old should they be to start sleeping on a roost? Is 6 weeks too young? They have been sleeping under mother hen or beside her in a small dog kennel they hatched in which is inside the chicken house. They have been sitting on poles out in the chicken yard so today I decided I would get rid of the box and put a good amount of sugarcane mulch in the corner where they have been sleeping instead. I have two roosts..one low to the ground and a second higher one. I put a ramp up to the top of nesting boxes which chickens can use to get up on the roost. I went up to the pen after dark and this photo is what I found. Chickens trying to hide under mother hen on the roost and using the higher not lower roost. Can they hurt themselves if they fall? The white one did come off and didn't use ramp I have down lower. It flew to the lower perch and then up to this one from the other side.
