Dang. That's awful. We've lost a total of 4 to coyotes this year. Weird thing is, it was two at a time that would come up missing - during the day. Had been letting them range when we were at work, but no more! It's almost as if they were saying to each other "alright, the humans are gone, let's move in and get a chicken dinner!". To top things off, our neighbors are now feeding a mama coon with about 5 babies (aww, they're so cute!) Ugh. They should know better too, as they used to keep chickens just a few years back and he would have to coon hunt at night. My husband has already told them that if he catches any of the coons around our chickens that they're goners. These are lovely, but clueless people. No more free eggies for you! Good luck keeping the rest of your flock safe. I know how maddening this is.
