Came home from work yesterday afternoon and when I opened the back door to let the dog out I noticed that about 10 of my chickens were running around the back yard. So, I go investigate. Human door and run gate all locked and secure. I was a little confused on how they got out. As I looked around I noticed a lot of leaves laying on the netting over the run and a lot of pecans and small twigs laying around the coop, run and pecan tree. So I look up and noticed that about a quarter of my pecan tree was missing. My coop is at the back of my property and power lines run along side of the coop and run. So, the electric company was by to do trimming near the power lines. So I can only imagine my chickens were completely terrified by that big pre-historic dinasaur munching on the pecan tree over their little heads (boom truck). The netting is secured with zip ties but there are points that that if a chicken were to panic and fly up against it could be easily lifted and allow them to escape. (only the light weight breeds managed to escape, the run fence is 6 feet high) I could tell the flock was stressed they were not enthusiastic about their scratch they get each evening and most were on the roost by 6 and dusk is around 7. So hopefully that dinosaur will find another tree to munch on today so my girls can have a litte R & R today.
