For those who say the males don't fight during their first year: that hasn't been my experience. Our BRs were getting pretty hostile to each other by the time they were 5 months old. Ultimately, none of them were really worse for the wear, and they all made it to slaughter on schedule, but that doesn't mean they were sweet to each other. A couple of them got pretty severely beaten.
Broad breasted birds might be different. I know nothing about them.
Also, do hatcheries sell turkeys sexed? When we started our flock, the birds were only available straight-run.
