Yup it takes up to 5-6 years to prove something out have fun!

An easier way would be to breed a spider to a visual albino then all your babies are 100% hets, so any spiders from that clutch are spider 100% het albino, then breed two of that type and get your spider albino.

Visual morphs always have a better chance.

As far as your hets go youll have a 25% chance of visual albino, thats per egg not clutch, if you have 8 eggs 2 should be albino, but its random, could have 8 albino's or none, all the rest are 66% het for albino.
