I had my first hawk casualty today. My head hen, Professor McGonagall, was attacked. I had just come home from a family outing, and I went in the backyard, and the hawk flew away from her. She was a beautiful barred plymouth rock! She wasn't the friendliest bird I have, but she was in charge. Almost her entire head was eaten. The other 7 hens were hiding in various places in the yard, and I tempted them into their coop/run and locked them up. I don't know how long I should keep them there, to let that hawk know that free lunch is no longer available. Also, would it help to make sure the dog stays out with them when they free range in the future? I'm so upset about this, but I knew it would happen sooner or later, since they're outside during the day. I put a bunch of kale in their run for them to peck at, and I hung up a little flock block in there to keep them from getting too bored. I wish this wouldn't have happened!!! I also wish I could have a rooster here to help keep the girls a little safer. Just sad about it. Poor girl, she was a really great hen.
