Well, after 3 years of no predators we have become complacent and not been real consistent about closing up the chicken house each night. So in one night 6 hens disappeared! Just feathers and blood in the hen house. Now my 4 remaing pullets and 2 roosters refuse to go back in the chicken house, preferring to roost in the barn. We found a very young opposum in the barn but I can't believe it was the culprit. Whatever it was it was large enough to kill and carry off 6 full grown Buff Orphingtons. I'm thinking either coyotes or a fox? And how do I coax the remaining flock to return to the chicken house?
