any thoughts on breed, what is rose?comb's connected to ?

These are my latest Roo's, Big Fella, Mr Gimp, and Mr T, The are all feral, and have adopted me, my original 2 boys were stolen last year and have not yet found their way home, they had straight combs and golden manes (they were a good size and very sweet) the sister, black, (sex linked?)she produced and raised these 3 chicks; one grey speckled with yellow legs the other 2 mostly black, previously the black were hens like the mum, the grey speckled with yellow legs became my 2 Roos. this time all 3 Roos!
my query is, these 3 boys ALL have rose crowns? 2 look alike, one is golden. The only Roo's I see around have straight comb?what makes the difference? also the golden boy has small eye the twins have big round eye? they are all from the same clutch, I am sure there is Hawaii bantam in the mix? Big Fella is a little larger than the other 2. they are just starting to crow 2 out of the 3 . Any one have thoughts on this?

All mixed gamefowl/feral stock cockerels. Very handsome boys - I do envy you folks out in Hawaii. You've got lovely feral stock. I've always fancied the idea of trying to smuggle a few eggs home on a plane the next time I visit... if they're tough enough to survive and breed on their own, surely they'd be good to infuse into domestic stock.

Rose combs are dominant over straight combs. apparently the local cocks are rose combed.

Mixed breeds.

mixed feral chickens

Thanks, I was curious about the combs, the chicken around here have straight combs. I have not seen this 'rose' comb on any of the Roo's in this area and there are a good 100?or so, that hang out down the road. Interestingly, each 'community' has a 'look' to them, you can recognize which part of town it's likely they come from.
I guess every once in a while someone steps out? but these guys were born here at the house from mothers born here at the house. it is not usual for 'strangers' to come into our yard, once in a while but they dont stay around.
When I ring a bell my guys come for snacks hehehe, if I'm late they line up looking in my door. I get jumped on and mobbed when I share peanut butter sandwich or bananas, 2 favorites, I have to make them wait their turns, it is quite funny to watch. They will all wait their turn until 'Mr Trouble' eats, then its a free for all? he is not aggressive, he is the smaller of the 3 boys and the easiest spooked but the dynamic, when he joins in, changes things. They are so entertaining.
