The first looks like a welsummer, we have a hen welsummer, they are on the cornflakes box lol! I'm not sure about the 2nd one, I'll have to look into it. Heres a link for yours first roo, tell me if this looks close since you had him for a while
I love the look of your 2nd rooster! I do not know what breeds they are but seeing the previous poster saying Welsummer for the first one... my wellies had dark chests (like the link that was posted). Perhaps he was a mixed breed.
The second roo reminds me of d'Uccles, but without the beard and leg feathers.... I know I've seen a breed like him before... But I can't for the life of me remember what it was called.
