I will try to get more details but she is from my school and her entire flock was wiped out. All were standard chickens and all 75+ were killed (this makes me say dog) The way they were killed varyed, some were gutted, some had no head, some just were limp with no visible injuries. She has something knock over her brooders and kill all her chicks. No foot prints or hairs have been found. She has hardware cloth the bottom 3' and on the top half is chicken wire. She said all wire was intact and there are tops covering majority of the top (not sure how much majority is) Lives in NC and our county doesn't have skunks. Any ideas?
