This may seem like a strange question, but we are having a big problem. Our two RIR hens who are 1 year old have gotten progressively more brave and are no longer afraid of anything, human or animal. They follow us around pecking at us whenever we go in the yard, thinking we have food (or we are food). If you carry anything in the yard, they try to rip it out of your hand. One of them attacked the face of my 70 pound dog to steal a rawhide OUT OF HER MOUTH!! They also follow her around every time she goes outside hoping she will drop something interesting that they can eat. And, if my little dog gets too close when walking by, they try to peck her face. These are all fairly new developments as the chickens have gotten more and more daring recently. We want them to have some fear of us, like most chickens I have seen before, so that if you approach them, they walk away. We have tried chasing them, it doesn't work, they either just stand there, or attack our feet! We have tried spraying them with a hose, but as soon as you put the hose down, they come right back. Does anyone have any suggestions about what we can do to make them afraid of us and/or the dogs?
