We believe our inflatable tube guy totally works. It gets moved around the yard every several days as I hear hawks are smart. Purchased a used one and saved a little money.
Your frustration is totally understandable here. I’m sorry that you’ve had to experience such a loss.
We have many red tails around and even a golden eagle on rare occasion. The coop sits on the lowest level of our hillside property, house is on the highest level. So I worry about predators...
