Our two gobblers have been killing our older chicken hens by mounting them to death. A 30+ pound turkey will crush an eight pound hen. I have lost two hens and have a rooster with a broken leg. You can see the turkey is on top of my hen as she tries to drink. It is time to cull at least one of the two jakes. Since turkey eat a ton in winter it is not useful to keep them around. We do not plan to breed them. The nice thing is that these giants provide enough food for an army. And my chickens can be safe in the yard again, until a fox comes by.
