I've recently started raising three hens in my backyard but I'm having a little issue. I have converted an 8'x8' side room of my garage into the coop and the adjacent 10'x20' yard into a covered run for them. During the day they go in and out of the coop to sit on the roost or in the nests I made for them, or to just to eat and drink from their feeders. At night, however, they refuse to go anywhere near the coop. I have tried putting a soft solar light in thinking maybe they don't like it too dark but that hasn't helped. If I pick them up and put them in at night they will immediately try to run out unless I close the coop door, if I do that they huddle in a ball in the far corner the entire night. During the summer and fall I don't have an issue with them sleeping outside, but when winter comes I would like them to be comfortable inside.
