When I was at work during the day, something came in and killed 10 of my 43 chickens. I have a welded wire run with hardware cloth on the bottom half and welded wire on the top of the run for hawks, etc.. I was just sick. The girls were giving me up to 3 dozen eggs a day. I got a small live trap and put two chicken heads in it and set inside the run after i locked the girls up for the night. This morning at 6 AM nothing in the trap and there was no way I was turning the girls out into their run. Gave them scratch grains and hay to bide their time with. Got home from work tonight and was going to go out and get the trap out of the run as my DH and I were going to make a couple of weasel traps thinking that was what it was and low and behold I caught a mink in the live trap after the chicken heads. It came back today to have a killing spree. My run wasn't as predator proof as I thought. I have set the live trap again and am doing some reading on a mink. Girls were traumatized even today as they gave me just 11 eggs, but I gave them sunflower seeds, cleaned their automatic water and talked to them quite a bit.
