I was told the white one is a buff Orpington and the black are olive eggersWhere were they purchased? The first chick is splash and others black but there are many breeds that come in those varieties. It's near impossible to tell at this age unless hatchery is given
Were they purchased from a hatchery?
A homestead about 2.5 hours from me
That's going to make breed determination quite difficult then! Waiting until they get a bit older should make it more clear
