I have a few hens who like to sit for a few hours at a time (Orpington, Barnezieux and ayam cemani). In the morning I'll find one or two hunkered down, but by the afternoon they are happily free ranging with the rest of the flock. Is there a way i can encourage them to stay on? I'd like to try to slip them some hatching eggs. Are eggs still good to eat after a bird has been on them briefly?
