I looked for the answer but didn't manage to get clear informations.
If I have a bunch of hens, but no rooster, hens will lay unfertilized eggs (AFAIK).
From what I read, hens will brood them anyway, but then what ??
How long ?
Will they notice at some point that the eggs is not going to hatch/gets rotten ?
Will they die brooding "for nothing" at some point ?
Eggs will rot at some point, what happen to the hen then ?
My main question is :
1) What happen to the hens and to the eggs if I don't pick the unfertilized eggs ?
2) What happen to the hen if I do pick some eggs, but not all of them ?
3) What happen to the hen if I do pick every single egg ?
2) and 3) are kind of related to 1), I can ask other questions if necessary, but I think it's close enough so that one answer can cover every scenario.
