Mystery Mottled Japanese Cochin Bantam Cross

Meet the newbies! They are cute, sweet, and the girls have been laying non stop since they got here! As near as I can tell, these must be a mix of Japanese and Cochin banties. What do you think? Does anyone else see other breeds mixed in? They lay eggs like crazy, so we are eager to see what hatches out. Mutts they are, but they will be a perfect start to a pet project of mine. ;)
Their egg laying ability is definitely impressive.  They are still in quarantine, but they don't seem to care. They still lay cute little cream colored eggs every day. Two of them have laid every day since they got here, one was broody, but after three days, she is laying now too. The little roo is very personable. He crows at us every time we come out the door. He is protective and very gentlemanly with this girls, clucking and cooing to them all the time and showing them the best food bits. I love his body shape and confirmation. His head was a bit picked because of competition with a few other (bigger) roosters, but the feathers are growing back already. I'll have to get some new pictures when he gets all feathered out again. Have a look at my great impromptu nest boxes! They Love them! I have bricks lining the bottom of these standard wash bins from Wally World, so they don't knock them over. Also a couple chunks of concrete in the bottom of the bigger bin. We already have these salt and pepper chicks all named. The roo is Chip. The darkest hen is Inca, the lightest is Crystal, and the medium speckled is Sprinkles. :)
