I'm going to take a wild guess: the cock is a dom pied spangle. The babies did look a bit violet to me as well - that's why I said I'm not sure of the colour. Why don't you PM Lindsey and Nev. They will certainly be able to tell. There are others as well.
I was close! Tell me does the cock has iris rings or not? If not, then it is a RP like Nev said (He's 99,9% of the times correct). Tasha said that the second chick is a dom pied spangle. If the cock is a RP then the baby can't be a dom pied.
