My father is a backyard chicken keeper. He has a farmette and for the past five years has been raising chickens and ducks, pheasants and turkeys. His first year he had pheasants, turkeys, and a wide range of chicken breeds. We had them in the horse turn out, and we built a coop with nesting boxes. W With in the year, they were all eaten by something. the next year we bolstered the turn outs defenses, adding chicken wire entirely around the exterior base, new set of chickens, same results. the following year we enclosed the entire turn out, built three a frames, and ran wire completely covering it. Things were looking good, we had chickens sitting on eggs in nesting boxes, the ducks were mating. Then suddenly within a week they were all gone. We inspected the entire perimeter, and found no tracks. there are no holes in the fencing. We have Coyote and Fox, hawks, coons in the area. Any ideas? I will try to post up some pictures of the coop tonight.
