We get our chicks from the local farm supply here. We've usually always had bronze, but the first year, and the 3rd year (this year) we have had BBW's. We only wanted Bourbon Reds for THIS year, but half died, and we got replacements, which ended up being a bronze and a BBW. (4 turkeys max each year) All are toms. Its quite a different feel. First year, we had 2 toms/2 hens. Only the 2 toms fought. Second year we had all hens. They would get a little aggressive with a duck or chicken once in a while, but for the most part, just laid eggs. They have a big yard to roam in, but they are housed in a smaller house at night. When I let them out in the morning, sometimes the biggest one will have blood on his neck (and he has no feathers in one spot-its bare-they've been just pecking him there). I've separated them during fights a few times. I know they just need to be out more. Our coop is a 10x10 closed off area, to keep the predators away. Now that they are big enough, they've been out for longer during the day. I think that helps, but still, I guess I can only do so much.Are you using the same breeders year after year, or line breeding? You might need some new genes in the mix. If you don't have enough property for them to get away from each other, there will be more fighting. Usually mine will bump chests and pull a snood or two, forming pecking order, but if they were crowded, things would probably be worse. Turkeys do better, the more room they have and too many inbreed them by buying all their breeding stock from one source! Every couple of years, I get rid of all my toms and get new toms from a different non- related breeder.
When the laying season is winding down and molting will soon start, turkeys usually lay fewer and fewer eggs, until they stop completely to molt! This is normal! Sounds like Dad is already Alpha and not being challenged yet. Too many turkeys in not enough room makes for more aggression. Turkeys do best free ranging on about 1/8 to 1/6 acre per bird, depending on size of breed and quality and quantity of feed. If hand raised, they are less aggressive and tamer, but raised by their mother, they will be better foragers, given enough room!
Like chickens, turkeys will fight to establish pecking order and since they are larger, you will notice it more, but it also depends on breed and genetics, or diversity in the genetics!
