Herptrader (I assume you were referring to me!), I feel them cockroaches at all ages. Small woodies are fine for them, right out of the egg. They're brilliant little feeders and if you keep them well they can easily be full size by six months of age.
M.punja: Breeding schedule? Cool in winter, warm in summer, eggs start being produced when they warm up, eggs are extremely easy to hatch and have a short incubation period. I spread very few around Victoria. Currently I only know of one person legally keeping them there, although there could be a few more. I know a few of mine ended up in NSW a few years ago. For a variety of reasons I've been a bit reluctant to produce too many or spread them out too freely. For some reason, many people seem very keen to abuse having them on paper. To my knowledge, I'm now the only person who legally keeps Delicate Skinks Lampropholis delicata, if anyone knows of anyone else keeping them, please let me know.
Luke: That's right, no UV is needed. Why should they receive it if they don't benefit from it? Because they get it in the wild? I don't give them mites, intestinal worms, frosts, predators or many of the other things which they recieve in the wild. Does that make me negligent? When I obtained the original ones, the breeder told me he'd raised them without it and never had any trouble. When I first hatched some of my own from that stock, years ago, I tried raising them with and without UV, and there was no difference at all - they were all in perfect health, grew at the same rate and produced healthy babies of their own. I'm open minded, but I've never seen anything which suggests that skinks benefit from UV. It is possible that without vitamin and mineral supplements they might benefit from UV, however, even with UV, they are often unhealthy without supplements. I'd like to try raising some with and without UV using unsupplemented wild-caught insects, but these days I just don't feel the inclination to get into that sort of project, it's the sort of thing I was doing as a teenager.
