I think the black ones (and red one) are cochin bantams (but could also be frizzles? I ordered 4 of each) but the two in the feeder are some of our easter egger bantams.. I think we do have two d'Uccles - one is super tiny, smaller than the EE's shown but it's not pictured and I don't think it's going to make it (we also had two DOA in the shipment, one I think was a porcelain d'Uccle and the other a red cochin or frizzle), but I've done what I can to get it eating and drinking so fingers crossed it pulls through.
For now they're in a concrete mixing tub inside critter nation cage (1/2 bar spacing, very escape proof)) - this was mostly just temporary to keep them closer to food/water/heat and it keeps them closer to eye level which makes it easier to see them all. Once I'm sure they've all figured out how to stay alive they'll be moved into a larger brooder cage with 1/2 HC.
