    I am collecting marans eggs and I have noticed that although they are the same size some are about 30% lighter than the others. I first thought that they are lighter because they are 10+ days old but some fresh eggs are light too. any idea if something is wrong with either heavier or lighter eggs? they all are from the same couple of marans.

    I know they may be too dark to candle but if you can, see how big the air pocket is.
    If you can't candle them, hard boil a light one and a heavy one and compare the air pockets.
    The 10+ day eggs are likely too old to incubate anyway.
    A light egg of the same size has to have lost more moisture - perhaps more porous.

    thank you.

    does it mean that I should choose to hatch heavier eggs? btw I tried to candle tinted eggs and couldn't. I guess my flash is not good for that.

    As long as they're fresh (under 7-10 days) I wouldn't worry about it.
    Sometimes looks can be deceiving. Eggs that seem the same size may not be. If they were a perfect sphere it would be easier to determine size but they're not.
    If you are concerned, weigh them the day they're laid and the day they're set and weekly during incubation to see how much they lose.

    ok, thanks. I plan to use a broody muscovie duck to hatch the chicks. at the moment that is my only option and I expect my duck to stop laying and sit in about a week. I don't want more ducks and I do want more chickens.
