This sounds inline for animals in their first year. Get prepared to get larger tubs. I have a few smaller males and a couple that are substantial in size. My adult males that eat all year are the ones I "allow" to be stressed the most. They do not have hides, they are in clear tubs, and are the ones my daughters play with. They are pretty much bomb proof. The ones that do go off food have a setup that is closer to what is on the caresheet with the exception that I am on ambient heat. I tried the smaller container zero stress deal on some of my males that go off food with absolutely no change in behaviour, so I was curious as to what may be different in Deborah's environment. I have a suspition that she tends to feed smaller and or less frequently than I do and it may have more to do with that than the smaller diggs. I don't know. Hopefully she will chime in.
As a disclaimer, I know my animals very well, I do not recommend experimentation to new keepers. Sticking to the caresheet will keep you out of trouble. And I am talking about adult males here. Babies need an environment that they feel secure in at all times
