I have a few questions about eggs that I might just be over thinking. I know that a flock of hens only still produce eggs that are infertile, but I have a small flock of hens and a rooster that are just a few weeks old. These are my first so I don't really know how the egg production differs by adding the rooster. I know that having a rooster add the possibility of eggs being fertile.Can every egg that the hens lay (several months from now) fertile or not ( also not sure how to tell ) be eaten. Also, if I decide later to try and hatch some eggs how can I determine from picking them up from nest boxes which ones to keep to eat and which ones to try and hatch? Thanks!
