I have five baby roosters sent last week with my chick order to help keep them warm. They are very healthy, growing like weeds. I can't tell you the breed. They're all yellow and wing and tail feathers are coming in white which could be several breeds. At any rate, I don't think they're mutts, just extras sent along by the hatchery.
I could arrange to bring them to you if you don't live too far away. I'm not too far from Edinburg, Woodstock, Front Royal, Winchester. I do get to Manassas fairly often to visit my Mom too, so along 66 east to Manassas.
