Cheers for the response.
Makes me feel a bit better but if it hatches, it hatches and if not then I'm happy still as long as the other 4 do. I would be happy with just one hatching to be honest with you, considering it's the first clutch I've dealt with myself but then it'll be a case of analysing why it was a 20% hatch rate.
Either way I guess I just have a rather exciting week (or two) ahead.
