Backyard visitors

Earlier in the week I had some visitors. I saw them one other day so I decided to save some old bread and feed them. They were not the least bit scared when I walked out to feed them. Once I started feeding a few, it seemed like the whole flock came. They came back the following day and I went out again to give them more bread. I try to make sure they didn't come in the yard because I didn't want them to get too comfortable and come up on our patio or yard. I would hate to have abunch of geese poo in my yard - YUK!
