I brought home 6 rescue hens and we have a great set up in our backyard. At night they all go up into the coop which is great but they don't like the roost. They prefer to cuddle in together on the floor, which is covered in clean shavings (I clean out poo each day). ive now taken the roost out to give them more room, but now wondering...as they are rescue chickens they would not know how to roost. How important is it for them to learn how to do this? Should I just allow them to sleep on the floor (is elvated, next to nesting boxes) or should I train them to use a roost?
