Yesterday my wife and I came home to see a blue heron standing along side our pond. We quickly counted our koi and discovered that the feathered beast took a baby we raised that had grown to about 6". It broke our hearts! My wife names all our fish and she is dispondant to say the least. We netted the pond with our winter net to protect the rest of the koi, but this morning the bird was standing along side again!
How can I keep the bird away? We have an owl perched on top of the pergula but obviously it doesn't matter. Help!
