The odds (might) are against me

A few days into letting my broody hen (orpington) lay on some eggs. Then I just realised every. Single. Chick. Is not purebred. They are all bantam X egg layer some might be full bantam. But there isnt a rooster of the same breed of any of my chickens. Will the chicks turn out fine?

They seem to be developing fine in the egg

They will be vigorous crossbreds as long as the eggs are fertile.

Thanks. What if one of their eggs ends up under another broody if I decide to let her have chicks. Are multi breeds possible?
