So, we lost our rooster Saturday (well, technically we culled him, but it wasn't a choice we wanted to make) and would like to incubate some eggs. We had been planning on incubating later in the spring, but weren't really storing fertile eggs for hatching yet. What I would like to know is how long after the rooster is gone can we reasonably expect that the eggs are still fertile? All of Saturday's eggs and both of the eggs laid today I have saved and marked for incubating. That leaves me with 8 eggs of known age and 21 eggs that may be up to two weeks old. I know that the older eggs are less ideal for incubating, but am wondering how long I can collect fresh eggs before it is a futile effort. We are thinking about setting tomorrow, but if the girls are still likely to be fertile for a few more days we can always push the set date back a little farther.
