That was our plan! We bought two adult females over 1500 grams. We had some problems with one of the older females adjusting, but that just means she has to wait another year before breeding. We are trying to get a younger male pastel to lock with the other and they seem to get into the right position, but they either have their tails covered or you can see no lock is taking place when you check on them. We will keep trying as it would be cool to have pastels on our first attempt to breed ball pythons. If our other girl comes around we may try a fall breeding with her to our double het for VPI Snow to make some 50% PH VPI Axanthics, 50% PH Albinos, 25% possible double het for snow, and 25% that will be normal. No way to tell what is what until we back breed it so this batch will pretty much have 100% hold back on all females to breed back to the origional daddy taking the long odds way of doing things!
