ahhh but you are missing the point ---> chicken math
What one needs to do, is have all ages, the young ones so you get eggs all winter, the older ones so you get nice big eggs, a broody or two, and a few for the pot. Cause then...well you have to get more chicks,,,,, and so on
Last year, I saw no decrease in eggs. This year my pullets did not hatch till the end of July (that is when the hen went broody) so the pullets just now started laying. If I had had them hatched in May, (when I mentioned it to my BO's) they would have been laying great this winter. but I am thinking (hoping) cause of their late summer birthday, they should not molt until after winter next year? My laying hens, went into molt mid November, add many stormy cloudy short days of December, and the eggs were slim pickings.
anyway, get a few, lose a few, get a few more... that is the mantra of the true chicken addict.
