Trim the tom's toenails. Provide the hens with saddles. Most importantly do not allow the toms to have access to the hen's nests and do not keep multiple toms with a few hens. I try to keep at least 4 to 5 hens for one tom. A single tom can easily handle at least 10 hens.
Turkeys are really tough and can recover from pretty bad wounds. They may suffer life long symptoms such as always having a limp. If you want to try to save her, do your best to keep the wound from becoming infected or filled with fly eggs followed by maggots. Blu-kote while not a pain killer...
If you have multiple toms in with a hen or a few hens, it certainly is something that a tom could cause. Typically the type of wound a bad mating would cause will be below the wing and in front of the leg sometimes being so bad that it is opened completely into the intestine area.
