Hi guys. I have given them long enough it's time I asked this question. I have some free range chickens ( about 25), they were in coops until summer got here and they came of age. Most of them are at least of laying age, with 4 or 5 a little younger. It is a mix of breeds and sexes. We have two large houses they can go in. One is next to the chickens that are in a coop (my layers). For the most part they find someplace to roost at night a few go in the house that is closesest to our house and the feed shed, but NO ONE uses the other house. No matter the weather. All of the houses have food, water, roosting rods, and nesting boxes. But this ONE box no one will use. I will say we did have a hen who used the box when she had 4 young chicks, and she did loose her life just outside the box, since then no one will use it. We cleaned it out and washed it down but still no one will go in. We have tried closing the door and letting them go in the small door, opening the big door, it isn't real high off the ground so that isn't an issue. We have seen them go in during the day to grab some food but they come right back out. We are starting to worry about the weather when it gets cold. Anyone have any ideas?
