My free ranging flock has taken the word free range to the extreme! I am constantly having to go over to the neighbors and bring them back. I'm talking well over 100 yards away from our yard. I have lost 5 birds since I started having chickens in May. I have got to start containing them unfortunately. The coop is a prebuilt (please don't judge. My husband runs our business and doesn't have time to build a coop even though we own a construction company ) The coop is off the ground with a big door to go in on one side and a small door and ramp on the other. There is a big door in front to collect eggs. The coop is 6 ft long by 5 ft wide and 6 feet high. For a quick fix I was thinking of enclosing the whole coop with a dog run but was wondering if there were any better ideas. We do have cattle panels that we could use although they are not 6 ft tall. And it's too muddy and frozen to hammer the t posts into the ground. I know a permanent run would need to have at least a foot of protection under the ground but for now I just need a quick solution until spring. Any cost effective suggestions?
