Ive hatched two chinese ootheca's. I used a heat pad and kept the tank humid and around about a month later it hatched, I dont think in captive the month really matters. Both mine hatched at late morning times but before noon, hope this helps but I'd try and be prepared at all times for the arrival :lol:I'd wait for more replies for hatching month as im not 100% sure, but I do know most hatch early morning.
