Rooster or hen

[Rooless]

If there are other, more dominant roosters around, he might never be much of a crower. It's not uncommon for boys to start crowing until 6 months or so.
These are four months old. The other two started crowing around three months old. Thanks for the help. I want to sell the roosters but wasn't sure if he was one. I'm disappointed I wanted hens.
