I had some chicks hatch in December (momma hid her little nest). We brought them inside since temps were -20 with wind chill most days at that time. I reintroduced them without any problems except one. They will not go into the chicken coop at night. They all huddle up in the same spot outside and I don't think it's quite warm enough for them to be sleeping outside since they are chittering. I've been putting them inside but I can't figure out why they won't go in unless the other birds are stopping them. Because I have other birds I can't exactly lock them in for a week. I did have them in a different coop inside the same run for a month but because of a small fire its off limits. They never went into that one either. Looking for any suggestions or will they just one day learn to follow the other birds?
