My lab herds my chickens and duck home, if they get to far! But turn your back on her and she will sneak into the coop, and eat every egg in there! Last night she got in and ate every egg my broody hen was setting on, 13 in all,with about 8-10 days to go, I'm so mad and sick to my stomach! I led her back in the coop, and let the momma hen peck her nose for a spell! I doubt she learned her lesson!!! She has been running to the bathroom if you know what I mean! Stupid egg sucking dog!
