Yeah my idea also that they should be pretty much the same.

this is a photo of the Calico Lesser Super Pastel on WoB

the pic's of the Buttered Rum are of hatchlings and this one already has some size so I guess they will color up the same and I guess the quality of the Lesser and Pastel gene play a big part in how they will grow up
