Back some 30 yrs ago, when redtails were extemely endangered, we were so proud and protective over a pair of redtails that took to nesting on our proiperty every year, raising young, within sight of our house. andwe have a farmyard full of chickens. And I never once even suspected they were bothering my chickens. Even as parents feeing hungry young, they didn't. They would sit and watch a lot, but that's just normal hawk behavior,they watch everything going on in their territory, actually seem to enjoy watching all the activity around a place with people and stuff. People see them sitting watching like that, I think, just assume they are sizing up their chickens, planning an attack.
