How often should I sort my Dubia colony?

[19nick93]

Hello, Iv'e had my Dubia colony for roughly 4 weeks now. I haven't sorted through the sizes yet because I'm not exactly sure when to. How often do you guys "sift" your Dubia colonies? I was planning on doing it today sometime depending on what you guys think.

Also, I have a question about nymphs. Will these grow into male/females too?

I honestly never sorted through mine, but I'm also super lazy...And as long as you don't feed off the nymphs till your adults are having new babies, they will grow to be adult males and females.
