One of the things that has been bred out of today’s chicken is the ability to go “broody” and hatch out a clutch of chicks. Chickens nowadays will go broody, but will abandon the eggs after a few days – the brooding instinct has been bred out of them. It takes 21 days of continuously setting on the eggs by a nice warm hen for the chicks to hatch out. None of the common domestic breeds available will sit the eggs long enough to hatch them out.
There is a simple standard feeding schedule for raising good quality pork and ham without excessive fat. And the first thing to note is that it does NOT include corn! I learned to raise pigs in Canada where the Canadian government pays a premium on top of the market price for each pig that grades out at a quality suitable for export as Canadian bacon. The standards are very rigid to get this extra bonus. It is a simple fact that corn fed hogs would never get that bonus. The bacon in our American stores is a disgrace. The fat content is indicative of a striving for weight and not for quality. If that is the quality of bacon and pork that you want, then read no further – just feed corn and enjoy the fat that you raise.
