Yesterday, while I was in the house an eagle was in the oak in the backyard screeching loudly. I ran outside grabbed my free ranging duck and put him in his inside pen. Later, that day I put him back out and stayed with him and the eagle returned doing exactly the same thing. The brave drake tried his best to scare him off before I could grab him. The eagle is an juvenile American Bald Eagle. The oak tree is also home to squirrels, could this be the reason for the eagle's odd behavior? Needless, to say, I woke up early and finally finished up his outside pen and covered it with aviary netting. I am going to completely finish predator proofing it later on this week but at least he can go outside during the day while I'm home. The duck actually seems happy to be covered. Am I being overprotective? Will I be able to let him roam the yard again?
