So we put the 6 week old chicks into their big girl brooder last week. It has a roost and plenty of room to move. They still sleep on the ground. I am just worried because my chicks last year when they were moved just went and roosted. Do I need to train them somehow or is it ok for them to never roost? When they get moved to the big coop with my other hens which do roost, will I have a problem?
