How to mark dates on eggs

[Ortiz5954]

I am going to put in a batch of eggs soon into the incubator that I collected, do I mark the date on them that I collected the eggs or the date I put them in the incubator? This is will be my second hatch but plan to have a hatcher this time so that I can add eggs as we get them and also be able to hatch both chickens and ducks. Thanks!!

The date you put them in the incubator.
I write the initial weight on my eggs also.

I don't write the date I incubate in them, but I record it on paper. I do make a habit of writing the date, weight and hen name on each egg laid. When I incubate (only 3x so far) or give eggs to a broody hen, I number the eggs and record the number and the corresponding egg info on paper too. I do this in case I can't read the writing on shells well later. It makes identifying the hatched chick a lot easier for me.

Good advise from both. Thank you! Egg thing will keep me and my daughter butting heads on what duck or chicken it came from also!
