Why do Red Tail Hawks leave prey uneaten?

[yomama]

Thank you so much. I figured it might be a matter of eating what they can and coming back for more later, providing the prey was still there. I am a stay at home mom, most days, and when I do work, its not for too many hours at a time, so it is not too often that my chickens go unchecked at least a few times during the day before they are locked up for the night. I most likely have interupted the hawks' process. It makes sense to me now that they go for the throat, since there is a major blood supply there, if they get their fluids from their meals. I was puzzled by that part most of all. Thank you both so much!!
