Grrr. This is my 3rd year w/free rangers and I've never had a problem with birds of prey before. But I stumbled on this today while I was picking up the yard in advance of the hurricane. All of a sudden out of the bushes walked a hawk/falcon. I thought - hmmm. A hawk walking... Then it flew to a low branch. That thing was huge, and beautiful. As it then flew away I noticed it dropped something, which I figured was a mouse/chipmunk. Our chipmunks have mysteriously disappeared, but I haven't seen predators after them. Anyway, I checked the brushy area the hawk walked out of, and there was one of our 10 week olds, a rooster chick, headless. As we were looking in the bushes for the rest of the chicks, I saw the thing fly low across the field and scare the grown hens away. I noticed the bird was brown in flight, with spots on its belly. I was thinking peregrine, but when I looked online, maybe it's a cooper's hawk. Every year this time a hawk visits our property on its way migrating south. I've watched it other years with a spotting scope, admiring it. I don't know if this it it, tho, it seemed too large and more brown. Still, I'm sure this bird is migrating and just stopping off for a week or 2. I will be GLAD when it's gone. Last year I loved seeing the hawk. This year I hate it. I've never had a hawk go after my chickens before, even when it visited in August, I think that hawk was too small, but this one, like I said, is huge. Now I'm thinking of getting a run, and keeping my birds penned up. I hate to do it, but in the longrun, it's better than becoming part of the food chain, esp. after all I invest in (and care for!) these birds.
