Who keeps a hen with their hens and who don't. why? I am asking because a friend ended up with 4 chickens when buying a new home the previous owners left 3 hens and a rooster behind when they moved out. someone told her that is she wanted fresh eggs daily she needed to keep the rooster away from the hens. This didn't make since to me so asked her why and her response really didn't make sense from my experience so I am asking here. More of this persons reasoning really didn't make sense to me.
