Hello I purchased a small colony of dubias to start breeding for my beardie. I have a pretty primative setup. Just a human heating pad on the side of the tub set on the lowest setting with a screened hole at the top for ventilation. Feeding roach chow and watering via water crystals. I have provided fresh oranges every couple of days. I was wondering if I should have my egg flats stacked vertical or horizontal? Also, should I have the heating pad on the side of the tub or the bottom? Thanks in advance. I do plan on getting a cheap stat and therm eventually just looking to get everything going now. Also seems I only have 10 males and maybe 100 females how many more males should I get? Thanks
