David Holderead a waterfowl expert and the author of this book was very informative in this guide to raising geese, I used many things in this book to stump 4-Hers. The only problem with this book is that it is outdated (I got it from Goodwill) and some of the breeders who were in there are not here much anymore and this was also the time before the Egyptian Goose had trouble in Oregon. Any Goose lover and those who are interested in starting will benefit from this book.
