Baby crickets hatching in an enclosure are not going to harm anything. The adults can and do. Ackies do seem a little on the tougher side of skin textures but I would say eye lids would be the most in danger while they sleep. Honestly, who would sleep unstressed with crickets milling around on top of them?

FR- I have seen enough lizards, mostly Iguanids, that have had the edges of the eyes chewed on and then healed nearly shut to a pin sized hole to not risk an animals health in that way. Anything I post on here is based on 20 years of husbandry experience and around 30 species of reptiles bred in captivity. I see no reason to artificially stress baby lizards with excess feeder bugs.
