I know this question has been asked a million times! But I have ten females and 11 males in a grow out tub (Separated by gender of course!) I am waiting til they get older to determine which males I want to keep for my breeders and I will feed the rest off! So my question is: When should I separate them into their own lil colonies for breeding? I was told they were 5 months old but they are very small and don't look 5 months old! What are some ways you guys do this? Or whats your guys's rotation?

Thanks!
