I have tons of egg cases and some looked like it hatched already but I can't find any nymphs anywhere. I separate the egg cases from the colony and put them in approx. 25L container with the ventilations on the sides with no holes on top of it (to keep the humidty). I placed the egg cases in a damp coco fiber substrate with some peat moss on it. It also has some water gels just to keep the humidity high. The temperature here is pretty normal for a tropical country. So my question is how long does it take for an ootheca to hatch? Please suggest some tips based from your experiences and from what you've learned. Some egg cases looks shriveled too. HELP ME PLEASE. Please tell me how you store them and successfully hatch them. Thank you very much!
