All my hens were fine this morning when let them out of the coop to free range (8am), then I found a pile of feathers and quite a bit of the carcass of my sweet Barred Rock pullet under the trees early this afternoon. Any ideas what would do this in broad daylight? My yard is completely fenced, so no dogs should be able to get in and out. I assume a hawk would fly off with her and not leave so much of the body behind?? Is there anything do be done to prevent this from happening again?
