I've been considering this for the last year or so, this winter especially had been tough on the feed bill. I have currently got 3 generations of chickens with my latest batch from this summer laying good and the old hens are kicking back in now too, the oldest are at their 2nd moult now, in going to hatch a new batch this spring and cull the older ones this fall with the exception of the one that the wife has as a pet and a couple of the brahmas and cochins for broodies. Hardest part is convincing the wife to stick with some more productive chickens
