My 4 pilgrims are great with me and my 14 yr old boy. They hiss and go after my wife (though she gives them a little kick and they always turn around and run off). They go after my 9 yr old boy, but he enjoys the "fight" and holds his ground. My 13 yr girl, however, is absolutely terrified. They "trapped" her in an outdoor shed a few weeks ago. I don't think they would do anything, but she was convinced her life would end violently at the hands of honking geese.
So, we no longer let them have unrestrained free range. A friend of mine suggesting snow fence as a moveable barrier, and this has worked great. It still allows them to free range, it is VERY cheap, and it keeps my daughter free to enjoy the outdoors. Plus, the geese had a nasty habit of pooping right on our doorstep and sidewalk, and my wife and I got tired of cleaning it up DAILY.
The snow fence pen is very large, so I only have to move it every other week or so. One down side, you have to learn to live with a very ugly orange fence in your yard.
