ID some rosters please!

[lisafromvermont]

my friend has too many roosters and i offered to take them to keep one and stew the rest. one of them is all white, huge with HUGE legs and seems too heavy for his frame and i wonder if it is a grown cornish cross. the others are black and white, two have feathered legs. wanting to keep the best one to impregnate my chickens. might a cornish X rooster mating with rirs, austerlorps and barredrocks make good meat birds?

thanks!

The two on the outside of the top photo look like light brahmas to me, but the middle one looks like it could be a different breed.
