Eggs- determining FERTILE from INFERTILE

[Edworld]

So i understand that if the eggs are fertile you should be able to observe an embryo in the egg if you put a light up to it, but how big is this embryo, is it always visible??
Also i find it hard picking the eggs up and placing them into the contained in the incubator, what are the best tool to use to pick up eggs from the breeding place?? spoon maybe, tweezers?? as i know any movement or shaping of the egg while effect the birth and embyro...
I think this info can help all so all posts would be highly valued!!!
Thank you

when the eggs are fertile they will be nice and round and white. when an you have an unfertile egg it will not be all filled out, it will be limp and smaller than fertile eggs. As for the seeing the embrio in the egg you can see the veins in the egg when they first are layed. Then over time you can see the actual baby towards the end of the incubation.

I would not advise you to use anything but you hands to move the eggs when they are first layed because the shells are still very soft and you might brake the shell which would lead to the death of the egg.
