I have an existing fenced area which I am considering using for chickens, but would like to know if it's suitable... It's around seven foot high, and set out in an L - shape around the corner of our home. Each length is around 12 foot long by six foot wide. Because of overhead trees, the one section of the 'L' is almost always in shadow, while the other section gets dappled sunlight. Would this be at all useable? My idea is to get fresh eggs for my family of four, and perhaps sell the excess at the local Farmers' Market. Thank you.
