The current issue of Mother Earth News page 42 under Raise Your Own Animals: "Plan on harvesting about 1 egg per hen per day". I have several years of experience with raising chickens and I have never had hens who consisitenly, year round, regardless of age lay one egg per hen per day. I have had some that were great layers, Golden Comets, RIR but they couldn't do that. BA, nope, wellies not even close. There is no specification of breed in this article so this could include any breed. To average 1 egg per hen per day some hens are going to have to lay more than one per day consistently to make the math work. I am curious as to which breeds even come close. Maybe I have the wrong kind of chickens.......or maybe this was written from an office by someone who either has a flock of super chickens she didn't want to tell us about or she is more comfortable in an office than at the chicken coop.
