After 40 years of keeping layers, I now have come to realize that in order for me to attract more customers to my certified organic produce farm, I need to constantly have eggs for sale. In the past my flock has ranged from a dozen to 75 birds. Now I have increased that to 150-200. I have a great coop with a bin feeder, concrete floor. well sealed house and yard. electricity and water, etc. Water has always been the most labor intensive aspect of it all. Constant filling of founts and dealing with freezing temps (zone 6, SW Ohio). I am now in the process of designing and implementing a plumbed, heat taped, nipple drinking system so I can maybe leave the farm for a couple days at a time.
