I have started small project on Wednesday setup small terrarium 60*40*40 with heat mat and led bulb temp around 29c on hot side, locusts adult from pets at home food rocket and Kyle this morning I have found half of them dead can you tell me what I'm doing wrong.
I don't know about locusts first hand but from what I've read your setup and temps sound right. Was there a big cooldown overnight? Perhaps something was wrong with their food or you just got unlucky with an unhealthy batch.
Ah that sucks would be they were old? I did find when I started to breed mine they needed quite good air flow, apparently they breathe through their skin and humidity causes suffocation. Not sure if that's if any use! Good thing you have eggs though, hopefully they hatch
