I have heard that guinea fowl don't make very good mothers. Last week she reappeared after one of her absences and a few days later we found her nest.
The eggs looks like they have been interferred with, rather than hatched. I think she has jumped off the nest too early and then something has come along and eaten the eggs. I am trying to encourage them to eat near a spare cage, in the hopes she lays in there and I can keep an eye on her.
I would love to have little babies running around!
