Hi, Ive bought 7 Blaptica Dubia roaches to start breeding them. They all matured 2 months ago. I've had them for 8 months now and nothing has happened except for the one of the females has produced 2 or three egg sacs but nothing came out of them. THey had dog food and water crystals. And plenty of space to climb around in with all the egg cartons. I have 2 males and 5 females What am i doing wrong?
