My five 19 week old chickens have been outside in their coop now for 3 and a half months and at dusk they always go in their coop and roost by themselves. Two weeks ago we added a roost in their run so that the girls can get a break from the maturing rooster and it gives them something else to do during the day. They were all still going into the coop to roost at dusk everynight like usual, but the past two nights they did not go in and we had to pick them up and set them in the coop. Which was a struggle since my rooster is crazy and he kept hurting the girls each time I would put another one in the coop. It would be nice to let them decide where to sleep and choose inside or outside but I only have hardware cloth on all the sides and top, not under the ground or run. Will they eventually learn to go in the coop on their own again like they did before? Thanks!
