I'm not sure myself but if you post this in the feeders section you'll probably get more views + someone might help you there. If you can post pics of your set up, what temps. they are at + how long you've had them it would be helpful.
BTW, are you in the U.S or somewhere else ? Jut curious, most people in U.S use dubia but I think that what are called " woodies " are used by Australian keepers . The woodies might be what we call " lobster roaches " , nauphoeta cinerea.
Oh, didn't know there was a feeders section still new to this. I'll post it in there today anways.
I I'm in Australia
They're speckled feeding roaches basically
My setup is just a 52L plastic container it has air holes I don't use anything to heat them up I am planning to put them into a metal drum since I heard they breed better in that.
