Wow, my heart is racing. I had let the girls out in the yard.... mind you we are in an EXTREMELY tight suburban neighborhood, and all the girls are adult-size standard hens..... and was keeping an eye on them from the office window. I had just, 5 minutes before, been musing "hmmm, wonder if a hawk would ever attack adult hens?" but not really worried about it. WEll----- must have been some premonition because suddenly there was a loud screech from one of the girls and I looked out to see a small hawk swooping down and then flapping away. I ran out in my bathrobe and stocking feet (it's about 35 degrees out!) and rounded everone back to the coop. They'd sheltered under a bush and were terrified. I checked everyone and there do not seem to be any injuries. This hawk was SMALL.... maybe 2/3 the size of my smallest girl and half the size of the largest. Is that normal for a small hawk to attack a big bird? Was it really attacking? Does this mean I can't let them out unless I am there with them? Wow, that was scary.
