There are no dumb or silly questions when you're trying to learn. Heck, if others didn't ask questions before I got a chance to pose them, I'd be asking a lot more.
I like to have a book in my hand rather than on the computer. I just can't stand to look at a computer screen that long and I can't bookmark the page and it just seems more overwhelming to me that way. A book is something that in my opinion, cannot be replaced. It's really nice that they're online now so hopefully I can get some of them printed out for my own use.
I agree, it is nice to have the physical book in hand. The copy I have of Call of the Hen is basically a photocopy and the pictures are just about useless, so I read the text over and over again to try and understand what Mr. Hogan meant. His writing style is very entertaining. He has one goal in mind only, and that is increasing the egg laying ability of a flock, which I think is extremely useful when that is a/the missing piece in a breeding program. As do many authors of poultry instruction as well as our fellow forum members with years/decades of experience, Hogan reminds the reader that vigor comes first.
