Dubia roaches/lack of males

[Bruce]

It's very hard to sex a nymph, unless it's body shape is more round than long, then it's probably a female. If you're using these roaches as feeders, at this point it should be ok to few of a few smaller females without harm to your colony! I wouldn't worry though, I'm sure you'll find once the nymphs mature you'll end up with more males than you think you'll get.

Thanks! I think I'm not patience enough.
