Defiantly can happen! Identical twins would have to be the same sire because both babies came from the same egg from the mother and split in two to make two babies. Fraternal twins are different. Two eggs are ovulated from the mother and each is fertilized by a sperm. If there are sperm from two different males present, each egg gets its own daddy. In egg laying animals, it is very possible for the mother to shell two eggs together which would make two babies (with two yolks hatch from one egg shell. Actually, I believe that fraternal twins is much more likely in egg laying creatures as opposed to Identical twins. More pictures once the babies shed. Enchi can be tough to ID sometimes before shed. Were there any other enchi in the clutch?
