yes i do monitor the dog, no matter how good they are it is in them to eat anything and he is a cocher spanial, which is a hunting dog, so i do think he would kill them if not out there with him, but then we even go out with him to go potty, to many out get taken right from the yard so we are with him at all times, never leaves the yard, as for the kids, they love getting eggs from coop but only come maybe in the summer, not like they are there all the time. we have 2 chickens them come to us to pick up, the kids know to only pick them 2 up.Sounds like you monitor your puppy and grandkids. It's when there's no monitoring that it's iffy about trusting pets or small children around layers. My Mom on the farm said to never trust little kids or puppies behind your back because they get into trouble in the wink of an eye and that's stuck with me all these years!
