We have red shouldered and red tailed hawks here and been told a couple of nesting bald eagles. I can see them going after chicks and pullets but are hens too big for them? Wouldn't a fully grown Light Brahma be a little large? I'd like to free range them in the yard but I can't be out there every second to scan the sky. Can't keep roosters but did read that the Anconas are alert to hawks and owls and thinking one of those added to the flock would be useful. Sorry I just saw a thread on this and don't know how to delete mine.
