You know when I first started keeping hens and read lots of info I do remember thinking, 'but what about..' so many times as there was such a lot of things I wanted to know and the books didn't tell me. I thought that anyone writing a book on livestock should do it in co with a novice.
As you keep them for years, you find out most things anyway and you forget what you didn't know. So don't worry that you're a novice, it's amazing how quickly you learn and the books do state most of the obvious things anyway.
Hens are fun, but we stopped breeding as we seemed to just be killing lots of lovely looking little boys and it was upsetting. I take the easy route just buying hens. If you do want to do the breeding thing in time, think about colour coded chicks such as Cream Legbar which have different coloured males from females.
Enjoy your hens. and your sheep, goats, cows, ducks ........
just all accidentally of course!
