I dont see to much of a prob with supers, yoshi at 1st had some digestive issues, just pooping out the occasional shell but after a few feedings it was just fine. At this same time he was on meds for parasites, so i dont know if that could have been a reason.
When i 1st feed him supers, i did it very slowly, 1-2 worms the 1st day, watch for poop, 2-3 the next day, watch for poo. etc, etc. . . untill he was in full swing.
I don't want to feed my girl supers yet, because i have about 1000 crixs that she needs to finish eating, since yoshi decided he didnt want to eat crickets anymore and now only wants dubia, and supers. . . spoiled kids, i swear!
