I guess it was worth a shot to ask. Thanks for the heads up on the preservatives. I'll probably offer hornworms as treats since they are expensive. I'm going to get a 50count of silkies from mulberryfarms and see how that goes. I gave him a nice treat of Supers over the weekend and he loved them (his husbandry was perfect and he passed them fine). Next on my list is to find a larger feeding bin.
The one that I've been eyeing is not too large and would still fit inside his enclosure, I'm pretty sure he'll adjust fine.
thanks everyone...no green silkies in Randall's future (unless there's a safe natural food coloring source

)
