Hey all! Between my sister and I, we bred 336 cubs last year (neither of us were on a whole lot). We both bred for combo bases whenever possible. If the parent was not a combo factor, then we matched the Genetics as best as possible. No breeding items were used to influence the outcome of the base. Here are the results:

Female: 284 (73.809%)
Male: 88 (26.190%)

Common: 294 (87.500%)
Uncommon: 9 (2.678%)
Rare: 31 (9.226%)
Special: 3 (0.892%)

Applicator: 1 (0.297%)
Breed Only: 30 (8.928%)
Combo: 1 (0.297%)
Custom: 258 (76.785%)
NCL: 45 (13.392%)
Exclusive: 1 (0.297%)

Mutations (visible at birth only): 5 (1.48%)

Which is very disappointing and kind of why we haven't been keeping track this year. For me at least, I have noticed more males being born to my ladies, but that might just be happenstance.

Has anyone had better luck with the same/similar constraints?
