Mystery rooster and 15 wk lavs

[ChiefSuperFly]

I've got a rooster that my mama gave me a year or so ago. He's a real well mannered fella. A friend of mine I call the chicken man said he looked part wyandotte. I don't think he's full leghorn but I feel like he's got some in him and can't they have a rose comb? The rose comb is a big beautiful thing. I just hatched out some of his chicks and several have rose comb. His girls are a mix group and the eggs I chose are from our leghorn hens.
The other pic if I can get it to load is a quick shot of my lav ameraucanas. They will be 15wks soon. Hoping for input on gender. Two look real red and two look pale but I wonder if it's a maturation thing. TIA
