Turkeys

We have had a family of 30 turkeys traipsing through our yard every day since they were born this summer. Now they are really big turkeys and they are overtaking our yard. They have learned how to fly onto the bird feeder and putting strips of nails on the top doesn't work either.
Just a few of our 30 friends and notice they destroy the pretty snow too!
Today this turkey flew up on the swingset and then flew to the roof and proceeded to walk the ridge all the way to the other end before flying down! If there are 30 this year... how many will we have next year?...
