So ik trying to breed a female Zubat but all the eggs keep hatching as guys, their parents are a ditto and a male zubat...why is it always a guy? The gender ratio is 50-50 but it seems highly unlikely these eggs are always male off that.
This is just luck. Unfortunately, that's just what it is. There is nothing that can indicate or change the gender of the offspring. You'll have to keep hatching until you find a female. Sorry.
Hope I helped. :)
