Re: [Killietalk] "no eggs"
Last year I received some Notho. eggs (2 species) from South Africa, approx. 2 weeks after being
laid, and these were ready for wetting 1 week later. Normal incubation period for these species are
10-14 weeks, which I have found to be correct from my own produced eggs. Thankfully the sender
informed me to keep a careful eye on the eggs and to wet them immediately they looked ready. If I
had waited the normal incubation time I might have lost most of them.
