My crew is about 18 weeks old. We put the nest boxes in last night and added the bedding and put a few more roosts in also. As soon as they came in last night the ducks picked a box and they bedded down for the night. None of the hens went in that I saw before I went to bed. This morning everyone was ready to go out when I opened their door, after I let them out I did a few more things on that side of the yard then went inside the coop to check everything and one of the Roosters was in a nest box. Do I need to be shooing them out or is it just the process of checking it all out because its new?
