I have two Rhode Island Reds that, until now, have been 100% free range. I'm getting ready to put up a coop for them. I'm just wondering how they might react to going from free range to coop after such a long time. (They're still under a year old but both have started laying.) I also want them to spend nights in the coop. Will there be a "period of adjustment" before they get used to staying in the coop at night? Will I have to go collect them from their current self-made nests and carry them to the coop? I'm expecting to have to do this a few times, but I'm wondering how long this might last? Any tips? I will continue to let them free range for a short time each day. I'm just wondering what to expect. Thanks.
