I got two new chickens yesterday. Any tips on how to help them get into and used to the roost and nesting area? I don't want to handle or stress them out too much. I put treats going up the ladder and a bit at the top but they only went up two steps. My next step was to take them and put them in there myself but again I don't want to stress them out since they are new and molting. Or will it be okay?
