Whatever it is, I'm pretty sure it's a juvenile. It does not have the reddish eyes of an adult. In late summer I found it sitting inside my run watching the entrance to the coop (where my flock was huddled). I let it thrash around a while & quickly closed the coop entry. When it didn't find the door, I had the idea of trapping it inside the run. As I was closing the door, I felt it's wings brush against the door. Not sure what I would have done if I had trapped it..... That hawk was either the same one- but slightly smaller - or a sharp-shinned hawk. If this is the same hawk, it grew, but the markings look the same.
Hens go broody when you don’t want them to… and won’t go broody when you do.
