Thank you.
As these eggs are nearly a week old I will be leaving them where they are until just before they are due to hatch.
When I get some more, I plan to remove them to a petri dish and attempt to make a time-lapse video of their progress.
If I can make one good enough (I am very critical of my own work, probably over critical) I would be happy to share it with everyone.

I do have an iphone and seeing that little gadget you sugested I just had to have one (Bit of a gadget freak here) and have just placed the order for one
Not sure if I should thank you or curse you for making me spend even more money
So for now I will thank you.
