There is a way with chicken eggs, so presumably its the same with duck eggs. There is probably a thread on here. Hopefully someone will be along soon to point you in the right direction.



I used to just put a few under my broody chicken and hope. Usually got ducklings <img src='http://poultrychat.com/oldforumIcons/style_emoticons/default/smile.gif' class='bbc_emoticon' alt='Smile' />

There is something about a small white mark on the yolk - I read it somewhere but can't find it. Something like there is a ring if they are fertile and a spot if not..............or it could be the other way round! <img src='http://poultrychat.com/oldforumIcons/style_emoticons/default/rolleyes.gif' class='bbc_emoticon' alt=':rolleyes:' /> I'll have a look and if I can find it I'll come back to you!

Could be wrong but I think it was one of April's posts, if that helps track it down?

Or you could just crack open a few and look for any difference.

All eggs have a tiny white spot on the yolk, the 'germinal disc'. If it's just a pale spot it's an unfertilised egg, if it's a bit bigger and looks a bit more like a ring with a slightly firmer, whiter edge, then it's fertilised. You mention a 'tail' on the yolk, I wonder if you mean the chalazae (white stringy bits). They're nothing to do with fertility, they fix the yolk to the shell so that the developing chick stays 'warm side up' nearest to mum. All eggs have chalazae, but funnily enough the ones in my duck eggs are smaller, thinner and much less obvious than in the hen/bantam eggs. So, every time you have one for breakfast you need to look for the tiny white spot on the yolk and check whether it's solid or 'doughnut' shaped - or you could just stick a few under a broody and hope for the best, that's what I always do! <img src='http://poultrychat.com/oldforumIcons/style_emoticons/default/biggrin.gif' class='bbc_emoticon' alt='Big Grin' />
