Hi there, we have 4 hatchies that have about a 6 week age difference. They are in the same enclosure. The littlest ones seem a bit skittish and are not feeding as well as the other two larger ones. Would I best to separate them now or just separate them at feeding time so the smaller guys actually get a feed. Also they love the crickets and meal worms but aren't really interested in fruit or veges. Should we be cooking the veges to soften or is grating enough?
