A bit of a late reply but I've been busy. Sorry...
The under developed opal that I got anxious with ended up dying just a few days later. I cannot tell you how bad I felt. Once those eggs have been opened it seems if they don't come out on their own they're doomed. I can tell you I won't be rushing anyone along this year. Now if I only knew why that one opal was so under developed in the first place...?
The rest of the clutch came out fine in the end. All the others came out a few days after my last post on this thread, 7 days total I beleive. I'd have to go look at my records but I beleive that clutch consisted of 17 eggs. Minus that one opal and I ended up with 9 lavender's and 7 opal's, no slugs. Not bad for my first opal/lavender breeding. Would have gone 100% if not for that one opal...
