I posted in another forum about a temporary playspace that I created using fence posts and safety fence. The next day, my son was in the playspace with the hens and a large hawk landed on the limb above the hen house scoping the hens in the playspace. I ran outside and the hawk flew away. The hawk was known in the neighborhood for over a year but I hadn't seen him in awhile. So the hens went back in the run, the playspace was taken down and that was that. Well, today while having lunch, I saw a reflection in a mirror of something flying into the back yard. The playspace was not up and the hens were in the locked run but the hawk apparently sees something he likes and is back checking out the coop.
