1. Average clutch size is about 6 eggs, per the Barker's book. Again, that number doesn't mean much because the number of eggs a female produces actually depends on a lot of other factors including but not limited to genetics, age, size, etc.

2. I think you are trying to ask "What traits will produce visible morphs right away when one of the parents are normal?" If thats what you meant, yes, a co-dominant trait like a pastel should give you visible offspring in the first clutch.

Deal with the morphs you like the best though, regardless of long its going to take. If you breed pastels when you REALLY just want a spider or an albino, save your money until you can get what you want - nothing is worse than feeding and cleaning poop up after an animal you don't really want to be working with.
