So, I got about 200 mixed nymphs to start a colony with. They ranged in size from about 1/4"-3/4" max. My question is this... I have had them for about 2-3 weeks now and I have been swapping food and what not every other day and yesterday I finally looked around at all of them to see how they are growing, a few are noticeably bigger (1"), but can't differentiate between male and females yet. But, I noticed probably 20-30 small, small ones, like 1/8" and I never saw those before. Is it possible for them to have already bred? Or am I losing it?
