Sexing juvenile turkeys

[Capricoco]

I have a group of turkeys I hatched earlier this year; They’re all around 4 months give or take, at this moment I suspect all of the pictured turkeys are toms. All are about the same size, they’re a mix of either gold Narragansetts, regular Narragansetts, red bronzes, or regular bronzes.
