Just keep in mind that there is one potential "fallacy" in using the Hogan method....ALL of the hens need to be in the same "state of laying" in order for the method to work. People who've used this method on hens that were "out of production" reported discarding as poor layers what turned out to be really good laying hens. Per studies conducted at Cornell University, "...When the system was applied to a flock of birds toward the close of the laying season it was successful in detecting the best layers because these would be the only hens laying late int he fall; they would be the late molting, persistent layers."
I can't speak from direct experience and in no way want to disparage Walter Hogan for the amazing work he did in helping people improve the overall production levels of their flock, but I also don't want anyone to go into using this process without knowing the potential pitfalls lest they be disappointed. I'm only sharing what I've found in my research. I hope to also use this method once my flock has reached maturity and progressed through their laying years and actually plan to "test" the limitations of the method first-hand to either corroborate or refute the finding of other researchers.
And if you're interested in researching of what I've said yourself, you can find the review I quoted in the book, "Judging Poultry for Production" by James E. Rice. This book and "The Call of the Hand" are my primary go-to books for determining my breeder selections for flock vitality and production.
I've been seeing recently some more references to the early molting issue affecting egg production - that early molters are going to wind up being your poorest layers. Long molters will be worse layers just because they are spending forever regrowing feathers, but the early molting concept was something that I had not thought about, even though it makes sense now that it was pointed out. That way they are only slowing down once, for molting and loss of light at the same time, rather than slowing down for molt and then slowing down for loss of light.
