Ugh Racoons are the worst! In 2009 when I joined BYC it was because I had a daytime coon! It skinned a cat! It needed to die, it was not well, possibly even rabid. Boy did I take a lot of angry responses when all I wanted to do was kill it. But whatever, you gotta do what you gotta do! This is going to sound silly now but I saw a coon on my game cam about a year ago, trying to climb my run. I broke into coon prevention, got a live trap, attached 3 foot wire to the top of my run (it falls over the outter top part and even coons are not smart enough to climb it.) And I installed a flood light out the back of my coop. I had to put curtains on my coop windows so the chickens have roosting darkness but I have not seen a coon again on my game cam for a year. It's not perfect prevention, but I do suggest the light, it really helps (with nightime coons.) So sorry for your loss but I'm glad you're picking up the pieces and outsmarting the little F ers!
