I like to run 1.3 or 1.4 in general but this season I have a male that ran through 8 females. (6 females have laid already)
It's a matter of how big your male is, how well he feed during breeding season and how smart you are about pairing the male and not do so till exhaustion.
OK.. do they go by age and weight for breeding? Please forgive been out of it for a while trying to reeducate myself
