I was in ND for 2 weeks for work. When I came home on Sunday I noticed one of my hens was in the nest; didn't think anything of it. The next day I saw her in the nest again thinking it was just that time again; coincidence. I just went out there again, still there same nest. I reached under her and there were about a dozen of eggs under her. Guess my family didn't think to look under there while I was gone. I have no roosters so I know they won't hatch. Is this normal behavior? Is she trying to hatch them, or is she not feeling well? Thank you
