I let my 6 hens out every night after I get home from work to let them free range till dark. Last night I was watching them while free ranging and all of a sudden the all froze. I caught a glimpse of a big bird in the corner of my eye and noticed it landed in a tree about 100 feet from where my chickens were, I noticed it was a large hawk that purched up on a branch. The hawk stayed purched there for about 10 minutes and my hens didn't move a muscle for the whole time. It was like looking at 6 concrete statues. They were all watching what the hawk was doing, I quess they were scared stiff.So I took out my pellet gun and shot near the hawk to try to scare it off, after the second shot the hawk took off and the hens went right back to pecking away at the ground. I was just amused at how they all just froze till the hawk left, and then went back to what they were doing like nothing ever happened.
