Egg weight Grams

[ChickChic00]

Does anyone know the best egg weight for hatching eggs. I'm thinking about doing an experiment with different weights for the best chicks. I have some that range from 40 to 60 and above grams. Any ideas or help? Thanks so very much!!

the advice I've read from poultry handbooks of various eras is pretty consistently in favour of medium sized eggs among whatever is normal for the breed you want to raise.

Incidentally, many of them are pessimistic about fertility at this time of year, if you're in the northern hemisphere and the cock and hen are or are close to moulting.
