My neighbor just got a few pullets, her 1st chickens. They needed time before they wanted to go inside and go up a ramp or jump up on a perch. Once they did, they started putting themselves to bed. I think hers were about 14-16 weeks old then.Mine are going back in but they just lay in a pile by the door all night. I built my roosts for heavy birds so probably 2+ feet high. They refuse to use them. I’ve tried putting them on after dark but they all scream and cry and just jump back down and run to the corner by the door again. They are 13 weeks old. Should I just let them be?
