Today was traumatic but fortunately not sad. Our five 22 week old hens were roaming our 65'x75' back yard. They usually hang by the back fence where there is dirt for baths, a satsuma tree for snacking and some shade from oaks. The middle of the yard is just open grass. Just as I asked my daughter (the chicks' "Mom") where are the chickens we heard a huge scream and squawk. I saw our brown lab mix in the middle of flying birds. First thought, the dog is attacking the chickens. Then I saw the hawk, with the dog in pursuit. We couldn't find the chickens at first. One had run back in the run and three had hidden under my sailboat. We couldn't find Priss. We could find LOTS of barred rock feathers. An hour of frantic searching in the neighbors backyards led us back home. I hadn't seen anything in the hawk's talons. She had to be here. One last idea search under a lumber pile resulted in a very traumatized barred rock and a very relieved 14 year old. Priss seemed glad to see us and came out to us immediately. She has a small scratch on her earlobe, is missing a bunch of soft feathers but has no other visible scratches. Still, she spent the rest of the day in a bin with litter, food and water beside my daughter. Roux, the dog, got lots of love, too. Now we have to figure out how to allow our chickens to cruise the backyard without becoming hawk snacks. We are building a low, PVC tractor frame and covering it with gray, plastic poultry netting but I see this as somewhat a pain. I'm looking for other ideas. I saw someone mention a scarecrow. Any thoughts?
