Rooster or hen?

[Tretinker]

The first one looks like a cockerel to me but I can't see it in any of the others.

Sometimes as early as 10 weeks but usually around 12 and well by 16 is when male specific pointy saddle feathers start coming in and are obvious. I do think I'm seeing them on a couple birds already (the first one and the colorful one with red leakage). Sometimes pattern can make rounded feathers LOOK pointy.. putting your fingers or a sheet of paper behind them can help discern true shape.

I’m positive the chicken in the last picture labeled number 2 is a hen. The one In the first three labeled number 1 kind of has me confused. I’m thinking a rooster but my husband said no. They look completly different to me from each other lol am I just blind and he’s right?
