I've just had my first loss of a chicken in my flock, I had originally thought it was a raccoon. I leave for work at 5:30 am it is just starting to get light and I let the chickens out of there coops before I go to work. I thought maybe a raccoon could have climbed the fence. What ever it was ripped off the head and ate 1/2 the breast, feathers all over the place. I went back out there today and surveyed the scene of the crime and found a feather that is not from one of my chickens. I looked on the internet and figure it was a Coopers hawk. My run is to big to cover with fence or netting so if anyone has any suggestions for me I would appreciate any advice.
