It will be easier to enclose the chickens at this point. My plan is to add a large 6x12 foot enclosed run to the 2 coops. (going to build a second one). Not the ideal but its about all the space I have that I can dedicate to the chickens. I also am planning to build an enclosed Composting section on my side yard and be able to send the chickens out there fairly often. (With the city ordinances I cant put them near the same place without destroying half my established garden.)
