A week ago I woke up to the sound of a THUD on my upstairs deck. didn't think much of it, thought a branch fell from a tree. It's happened before. Then Saturday Morning heard dozens of Crows making lots of noise in the Trees. Went outside and there they have a HUGE Owl surrounded on top of a Tree. They keep attacking it and it flies a little further away, eventually the Owl takes a LONG flight out of sight. Then I notice one of the two new Black Muscovy Ducks I have is missing. I got them a couple weeks ago and they wouldn't go in with the other ducks at night. They would fly up onto our upstairs deck and settle there. Now there was only one, so I figured the THUD I heard the night before was the missing Muscovy Duck becoming "WHO WHO's" dinner. Then last night we got side tracked and forgot how much earlier it seems to get dark out. Suddenly, our Geese came up to the Door and started tapping. That got our attention. My Wife ran out and saw a HUGE Owl swoop down and pin our Prize Drake to the ground! She scared it off. The poor little guy had some small puncture wounds but his feathers were able to protect him and the Owl didn't have enough time to really sink his claws in. The Drake is doing fine now. But now I know what happened to another Chicken and the Muscovy. I don't mind having Owls around with all the squirrels and mice for them to eat, but now they want Poultry? I DON'T THINK SO! Anyone have any advice on how to deter them?
