Wow I put in a nickel and get out a dollar ! Thanks so much Dani . It looks like I will have a about a month between when my correct sized feeders will be too big and a new batch will be a quarter inch in size , and ready to feed. I'll have to go back to fruit flies. And.... the calcs for the "house cricket" in Flukers , may not be the same as my wild caught , now cultured central American black crickets. No pet store with rickets or THOUSANDS of mile. So much to learn. The saying in Spanish is "poco a poco" little by little. Las question for now..... how big are the holes in the screen that you used to prevent the adults from eating the eggs ? Mike in Costa Rica
