I made a little "bean counter" for the bottom of this blog-page. (You can scroll down to see it.) I will update it periodically, as I tally the eggs I find in the bottom of ET's cage. I will keep them together by month, so next month I will start a new incubation container.
I guess this is a good time to mention that I would be happy to send these little beans to anyone in the USA who would like to grow an ET of their own.
