Or maybe fratricide? I had a hen setting on a clutch of at least a dozen eggs. This morning I see her wandering the run with the rest of the flock and a bunch of feathers strewn about. Maybe they're hers or maybe some other bird's. And her clutch is smashed. Moreover the dozen or more eggs that should have been there really look only like 5 or 6. I wonder if cold weather would lead her to get off her nest? Where did all those eggies go?
