Yesterday I bought 4, 17 week old pullets from a farmer. I put them in the coop so they would not be stressed and they stayed in all day. I locked them up at night and today the doors are open and non of them have ventured outside. Where they were raised, they never went outside. I'm afraid to take them outside because I don't think they will know how to get back in the coop (it has a ramp). I don't want to have to chase them down and put them in at night. Question: should I just let them finally come out on their own?
