I'm still torn on my opinion about breeding young or small females. Ultimately I guess what is meant to happen will happen. If she is not ready then she won't produce any eggs. I haven't heard of any females dying from breeding attempts but I suppose some could not be ready yet, get stressed and immunocompromised, and get sick in one way or another. Another downside would be if she produced a clutch of slugs, or mosly slugs, then that was pretty much a wasted breeding attempt, and wasted months that you could have been feeding her regularly to get more size on her. Also I'm going to make a generalized observation that smaller females lay less eggs than larger ones, so would you rather have a small clutch sooner or a larger clutch later? I'm not sure if there are any dry cut right or wrong answers here, but those are just some thoughts of mine.
