Another thing I wanted to add, on the subject of hawks, I have seen one try to fly off with a smaller pullet. It dropped it at about 10ft in the air but it did try. To me that says that if its prey were smaller, it would've carried it off. Maybe it has chicks, who knows. After dropping the bird, it perched in a branch about 20ft up directly over the yard it got the pullet from (my backyard neighbor).
This was a large (well over a ft long, head to tail) dark, charcoal grey hawk. Seemed to be all one color. Only the head was gone from the victim and it wasn't lying around in the yard so it was likely eaten.
When I walked outside, it was as though I didn't have chickens at all. Not a peep, not a leaf stirred; everyone was well out of sight and range. Same at the neighbor's place.
The other day a grey egret flew over, the bigger ones froze in silence and the younger ones ran under the shed. I know when a hawk's been near bc of how they behave. If the yard is dead silent, it's been around. Its almost like they can create the absence of energy.
Funny story: My neighbor has a bantam rooster that he says has been picked up before by that hawk. He said the roo started crowing while being carried off and the hawk dropped it.
Same rooster was picked up (and dropped) by likely the same hawk, all of his birds went nuts and his
amazon parrot, who could see it all from the window, started screaming "Bad bird! Bad bird!"
ETA: I live in the central part of a fairly small town. On the main hwy, lots of neighbors, old houses. It's pretty busy where I live but we're not far, flight-wise from woods and rivers.
