Trying to figure out the breed for these two. The solid black was supposed be jersey giant and the other with brown collar was supposed to be a black onyx.

Difficult to say for sure, but that could well be correct. Jersey Giants get big but they take a long time to get there, so the black one could be one. Mystic Onyx should have dark face and skin, but there's always the oddball that doesn't. Or it could be a legbar x black copper Marans type of olive egger.
