I know this is an older thread, but I thought I'd chime in anyway. There is a HUGE difference between Golden and Bald eagles, so comparing them to each other is not fair at all. One is an opportunistic carrion thief, geared for hunting fish and the other is a very active fur and feather predator. The ole Bald eagle is not very noble in agricultural areas where there heads can be brown from sticking them inside rotten pig carcasses dumped in the fields for fertilizer.
I live out in the middle of the country in Iowa and we have Bald eagles everywhere in the winter. I mean they are thick! Our property has a creek/tree line running through it about 150' from the house/barn area and every winter we have 5-7 eagles in the trees at all times. Our flock of 30+ chickens and 25+ guineas free range every day, rain, shine or snow storm and we have never had one taken by a Bald eagle. Even during week long periods of -5 to 5 the eagles do not bother the fowl walking directly under them. I am not saying they will not do it, but it is not a common occurrence. The same goes for Red-Tailed hawks. As a rule a hawk will avoid chickens, but like any population of animals you will get some that figure out that chickens are fairly easy to catch and they will continue to do it. These individuals are the exception, not the rule.
Great Horned owls are deadly to ANYTHING, no doubt. Most chickens are safe from them since they will be locked up at night. Coopers hawks are deadly on pigeons and young fowl. Most of the time they are moving through the area and
won't stick around too long.
I know that a TON of raptors are disposed of by well meaning but uneducated people. Not only is it illegal to do so, but it's a shame since the culprit us usually not the one that get's disposed of. I have flown hawks (falconry) since 1993 and I can tell you that 95% of the time when people blame hawks, falcons or eagles they are not the responsible party. A good way to tell is if you find a pile of feathers in a 2' circle, it was probably a diurnal raptor. Owls can pick up and fly off with something the size of a rabbit, hawks cannot. Hawks are stuck eating what they catch, where they catch it. If you think it was a hawk, check the closest bushes, grass, etc. because that's where they would have drug it to to eat, they hate eating out in the open. A Bald eagle that wouldn't look twice at a chicken will pounce on a Red-Tailed hawk down on prey in a heartbeat. Many falconry birds get killed each year by other raptors. As a general rule, big raptors eat little raptors with no opportunity missed.
If you have a problem with raptors bouncing off your pens there is a good chance that a falconer in your area would gladly/legally set up a live trap and remove the offending bird for you.
