Those two boys just look like muts to me, right off the bat.
That's also a lot of comb growth for 2 months. I'm going to say cockerels for the 2 in question.
Put them in a dog kennel so they can both see each other, and do that for 2 weeks.
(If you free range) I like to let them free range together after the 2 week period.
Their beautiful!
I don't own a horse, but I interact with a dozen, or so horses at the neighbors place.
They let me ride, feed, and just hang out with them.
If that is the case, you got pretty great odds!
Oops, that's my bad. The 3 single combs are gold sexlinks, I believe.
Not sure what the other 3 are, as for breed.
Yeah, I think you were right to assume that, I think that same as well.
Production breed are pretty good, that only ting that I've...
