Day 16. I'm starting to weigh my eggs daily now as the Ameraucana eggs are already where they should be at day 18 (some even too much lost) - one is at about 10%, one is at 13%, three are at 14% and one is at (ulp) 18% of original weight lost. The Marans are all around 10% with a couple at 9%. I think the one that lost 18% may be a porous egg, but I don't remember it looking porous, I'll have to candle it again and look. Anyway, I know I need to get the marans to at least 11%, and the outside window is 16% (according to various sources) so I'm hoping this whole experiment will work out okay... I decided I won't candle again til lockdown.
