so this morning i get a phone call from my grandmother that my chickens were dead. so i jump in my truck and drive over there and find 4 of my 9 chickens dead on the coop floor. Carlos my EE, Dragon my RR, Snowball my Black Australorp, and Sissy my Buff Orphington. dragon looked to get the brunt of the attack as she was always the protector and she was in one piece but her neck was completely stripped. Sissy was in the corner with her head taken off, and carlos and snowball looked untouched except their necks were bare and broken. my last 5 hens are freaked out and missing feathers across their necks. i thought our coop was rather critter proof with having 1/2" chicken wire and concrete poured all around. but after some recent renovations we missed one section. what ever it was it dug under our framing and got in and out. now we have concrete all around as well as sunken wooden boards and about 300 lbs of rock around the whole coop. my remaining chickens were so scared today they wouldnt even go outside they stayed in the "new wing" all day.they did eat and drink but i feel like crap. i love my birds and am so ticked i didnt build my coop better in the first place.i hope that my newest saftey additions do the trick and my girls are safe. now i need to raise up a couple more babies and hope for the best.
