Today, we let the girls out because my husband was working in the yard, and we thought that would be a deterrent. It wasn't. The hawk came out of nowhere, and my husband saw it in his peripheral vision. Thankfully the girls scattered, some into the run, some under the bushes. All are accounted for. My husband is furious! I guess now we will have to sit outside with them and not take our eyes off them. I am guessing by the time of year that it is a juvenile hawk...you know brazen and full of hormonal rage.
