My guesses:
Ancona? Yes
olive egger: Yes
Blue? This could be a number of chicks from the rare breed assortment. It could be an olive egger, blue andalusian, blue orpington, blue americauna, or blue maran. Can you see any sign of a comb? Fluffy cheeks?
splash?
Again, could be any of the blue breeds listed above. It doesn't look like it has fluffy cheeks. My guess would be an Andalusian
black copper marans? meal maker? Does it have faint feathering on the legs? It could also be an olive egger if it doesn't have feathered legs.
the other olive egger? possibly
white marans? or meal maker I would guess this is the meal maker and probably a white leghorn. Can you see a small single comb?
golden cuckoo marans??? olive egger?? That looks like a golden cuckoo maran.
