Yes, American orps are considered heritage All 3 “types” are considered dual purpose, they’re meant to be meat birds and egg layers.
My silver laced orps actually lay quite well, almost daily! Working with laced birds is difficult, MANY culls will have to be sorted through to try and pick the best out of them. I’m having a hard time growing out nice babies from my new sl cock. He’s got great type but his babies aren’t great as far as lacing goes. I’m going to replace him with my original boy who gives me babies with amazing lacing, I’ll be working on type more with them

.
Some one I highly recommend for buffs is Daniel Velazquez, he’s got amazing birds that are closer to the British standard. Or Jerry Craig Couch for American orps
I don’t keep everything I hatch, so the babies I raise I toe punch.
When it came to my bbs I was breeding 2 separate pairs, so I would toe punch the chicks the male from pair 1 on their right toe, and the chicks from pair 2 on their left toe. I only raised about 10 chicks from each pair, I raised them together. Maybe I should use wing bands lol, it would probably be more helpful.
