I have a hen who is sitting on one egg and will not get up. I assume she is broody and is going to sit on this egg for the forecasted 21 days. My other 3 hens usually all lay their eggs in the same spot where she is sitting. Will she move and let them continue to lay there? Do I have to be concerned about eggs at different stages being incubated by her? Do the other hens usually respect a broody hen and lay elsewhere? I'm new at this obviously, and yes I do have a rooster with my hens. Thanks for your help.
