Much of this time was spent fantasizing about one day having a 1/10th or 1/4th acre homestead. During that time, the book was eye-opening as to what is possible with that little space. Having soaked up these ideas about raised beds, chickens, dwarf fruit trees, and so on for so long, when I finally got a house recently, I knew exactly what I wanted to do with it, which alone is probably worth the price of the book.
But now that I have fruit trees to prune and chicks to raise, I'm not looking to this book for information. For building raised beds, I'm using the instructions from The Urban Homestead (Expanded & Revised Edition): Your Guide to Self-Sufficient Living in the Heart of the City (Process Self-reliance Series), which also details composting with worms, reducing your reliance on the energy grid, and using water more intelligently -things The Backyard Homestead doesn't even mention. Or take pruning. On page 111, "Pruning a Fruit Tree in Four Steps," Step 2 says "First shorten the branch to about a foot, then undercut the branch slightly before sawing it from above. Finally, saw off the stub, leaving a slight collar to promote good healing." These are just the kind of clear-as-mud directions that would greatly benefit from an illustration; unfortunately all that is there is a drawing of a man sawing a branch with a long-handled tool of some kind, nothing to show what exactly a collar is or how much of the remaining foot qualifies as the stub or even why he selected that particular branch. So for pruning, I attended a workshop presented by my local nursery, which was far more informative and has the advantage of pertaining entirely to where I live. Regarding chickens: There are some interesting points, like letting a fresh egg age in the fridge a week before hard-boiling so it won't be difficult to peel or selecting a dual-purpose (egg laying and meat) breed because they are more disease-resistant than specialized breeds, but nothing that will in anyway get you started. For that I'm presently using the book Chick Days: An Absolute Beginner's Guide to Raising Chickens from Hatching to Laying. For rabbits, you'll get two pages most of which just informs you that there are different breeds.
The only section of The Backyard Homestead that I was able to test out in my apartment days was the section on herb gardening. I killed all of them, until getting Grow Great Grub: Organic Food from Small Spaces), which revealed why the rosemary survived but did not grow (too small a pot), why the basil died (unrelenting exposure to wind), how all of them could have benefited from mulch, and how to make simple plant foods. It also explained terms I had seen thrown around in several gardening books, like the warning to not let your plants "bolt" (which at the time I could only imagine involved my herbs running away to a more competent home). All those other books have unhelpful charts describing the exact conditions favored by each plant (type of soil, pH, full sun vs partial shade, etc) until you believe each plant should be grown in its own meticulously placed test tube. And I spent years thinking "partial shade" meant some kind of sparse, broken shade, like under a tree. Turns out the "partial" refers to time; 4-6 hours of direct sun per day compared to 8 hours of direct sun per day for "full sun." And if you've always wanted to grow herbs, but wondered what you might do with them beyond cooking, then absolutely get Making It: Radical Home Ec for a Post-Consumer World, a brilliant DIY book on everything from making your own shampoo to beer to how to slaughter a chicken (The Backyard Homestead refers you to other books for any slaughtering instructions).
By all means, get The Backyard Homestead. Pour over it for hours in a coffee shop/bathtub/Cracker Barrel/escape-of-your-choice. Gaze lovingly at the beautiful, orderly homestead layouts at the beginning of the book. But think of it more as a course catalogue for college, that thick book (if they still put those out) that lists every class a college offers along with a brief description for each, rather than as the classes themselves. Use it to sketch out which topics you'd like to study, then find other resources (mentors, workshops, youtube demonstrations, books, meetup groups, feed stores, nurseries, magazines like Urban Farm) and go from there.
