I am just sick. I had 27 meat birds in a chicken tractor that had lattice attached to the sides on top of chicken wire. One panel of the lattice has been torn off, 20 the birds are dead in the tractor and 7 are missing. These were large cornish x, about 3 weeks from butcher date. It appears that something climbed up the side, ripping the lattice panel off in the process, and pulled the chicken wire down from the top and crawled in. There is no other point of entry. So whatever it was had to pull 7 whole birds up and over the inside of the tractor at a 45 degree angle (it is triangle shaped). What could have done this? There is very little blood and only one of the birds left has any marks on it on the breast but nothing major.
