^ Good point on the broad breasted. I was assuming heritage. You might have a growth/size issue if you have the meat turkeys. You don't want them out-pacing and squashing the chicken chicks!
My heritage hens that were raised with my chickens roost with the rest of the flock. My tom roosts on the coop and keeps watch.
He tried to breed the chicken hens only briefly when he was about 9 months old and the same size as them- the turkey hens hadn't quite matured. But even with just 2 girls he never goes after the chicken hens- though I recently got him 2 more hens, so now he's extra happy (and to be fair so are they!).
My tom doesn't fight with my roosters. My flock dynamics are very laid back and peaceable. I brought a new rooster in last fall and witnessed the most hilarious turkey intervention- my subordinate roo and the nee roo were kicking and hackling up, just duking out where they stand with eachother since he's a new comer. My tom approaches, places himself right inbetween the two hackling roosters, stands tall and puffs up, throws his wings out, and slaps both of them upside the head, toppling them over. He let out a big ole gobble and strutted away. The roosters sheepishly went their separate ways. Pip is the king of the roost, everyone knows it, no one challenges it. I have 3 roosters with him and there is no lack of peace between them.
I think a lot of keeping a tom, just like a rooster, depends on his disposition. If he's anything less than pleasant, why keep him around?
