Definately two cinnamons and one green, and the two cinnamons are female and the green in a male (50% chance split cinamon). Dad is split cinnamon and mum is normal. Possible that the parents are split pied too, but unlikely because you would expect pied babies if both were split. My guess is perhaps one is split pied and therefore the babies could possibly be split pied too! Do either parents have white toenails? this is a good indicator of a bird carrying the pied gene, however, not necessarily always 100% correct.
