Right... but I was trying to say that "profitability" depends on what you are selling. I'm way too small to make a profit selling eggs for the table. Even if I had 30 hens, and cycled them out every year or so, there wouldn't be much point. I'm more interested in the folks I meet who are upset that their Orpington had a blowout after 2.5yrs and now Esmerelda is buried under the new apple tree with a plaque bearing her name; and now they are wary of buying another hen. If Esmerelda had been bred more to give 200 eggs a year steady for 5 or 6 or more years instead of 300 or so for 2, these would be happier folks. My flock should feed me and my family meat and eggs cheaper than I can get at the store (check) that's money back in my pocket... then, sell hatching eggs and chicks, and sell my non-breeder but still laying older hens (that make sense, thank you!). Not what he was after.All chickens are really this way. The hens keep laying, but they also eat more an more with each passing season, making those eggs more and more expensive. Although holding onto exception producers into old age as breeders in order to retain and promote their genetics is important, the tops for maintaining a groups of birds for profitable egg production is 2 years--heritage or otherwise. Indeed, for a breeder, one idea make be to keep all of the pullets in a laying flock for a year, selling the eggs, and then moving yearling hens forward into breeding pens after they've proven themselves.
First I'd heard, though that the older a hen gets, the higher the feed-to-egg amounts... are there numbers for this? I'd like to know the amounts for figuring out MY break point
