Like Deborah said, Its dependent on size and age.

Aswell TBH I will never go above a Med sized rate even for my bigger girls at 2,000+ Its just overkill

My males stay at small rats, Females at medium

Even on small my males constantly are growing just not massively like the females.

Aswell When im 2-3 months away from breeding i will offer the them food more frequently, Not power feeding as they have size but to get up fat reserves on them, To reduce slugs, infertile eggs, aswell knowing my males and females will sometimes go off food!

I fallow same Ritual as deborah, But when breeding coming up i offer females every 5-6 days, vs every 7-8 days! If they take yay, if they dont ohwell!
