I am interested in getting or building a chicken coop for the side yard of my office building. The area is 90'x17' with fig trees, peach trees and vegetation. I would like to have enough eggs for my home and office. We are a family of four and and office staff of 7 (we have a kitchen and cook regularly). Im wondering how many chickens will lay how many eggs? What type of coop would be recommended etc. We are a construction company so building a coop would not be a problem if I had proper drawings but I was wondering if buying one would be cheaper. Any help is greatly appreciated!
