So I started a small dubia colony a few weeks ago with like one pair of adults. It has been doing alright, but two days ago I saw a guy selling lots of dubia roaches. I contacted him and he sold me 100 females and 30 males, along with thrown in nymphs for $40. So they have only been in the bin with my other roaches for two days but today I noticed 6 of the males were all dead in the same spot in the bin. Anyone know possible reasons for this? They came from a colony with like 15,000-20,000 roaches if that could have something to do with it.
