I'm coming at having chickens from a business-plan background. I would like to know what the average time is put into caring for 4-5 normal size chickens on a daily basis? Looking for a list of specific duties and average time they take, for example. Opening the hen-house in the a.m., cleaning the average free-range urban backyard, collecting eggs, cleaning the run, putting them to bed, cleaning the coop, and so on. thanks!
