I really don't like to have tom turkeys in with the chickens unless they have a LOT of space. If the tom tries to mate with a chicken hen (and in the spring they will mate with about anything!) it will end very badly for the hen. I lost a few hens because of that before I figured out what was going on...
At least your tom didn't mate with a ROCK!!! I guess Rosco (my tom) was feeling lonely!
