Some Ponderable Pages

I'm having a bad health day. My fatigue problem has flared up and even a cup of weak instant coffee hasn't helped. (I carefully avoid caffeine most of the time unless i'm really stuck in a drowsy fog, and then i try to take only just enough to perk up to normal. I used to be addicted and quitting was 10 weeks of hell because of how the fatigue issue deepened and extended the withdrawal.) So, i'm just going to post some links.

Keeping hens in the city
I want to talk about this another day. Free range hens are easy to keep, and most modern breeds lay an egg almost every day. Fresh grass  is the key to healthy Omega-3 eggs. Make sure your hens get occasional bugs, and feed them a few choice scraps, and you will be rewarded with highly nutritious eggs - each one is a veritable vitamin pill. Look at this article - eggs are good for you!

100 lbs. of potatoes in 4 sq. feet
How about that, a year's worth of potatoes for one person from one teeny patch of land. That makes a mighty big contribution to feeding yourself from your yard. Plus, if you get a composter going so your soil is rich in nutrients, those potatoes will be way healthier than factory-farm store potatoes.

Eating Mealworms
Abigale's Edibles is a great blog about raising and eating mealworms, and why that is such a great idea. You will need to buy the oats or other grains they need for food, but compared to any kind of standard meat, you get way more protein for the food fed to them. Plus, it will give you the bug treats your chickens so love in the winter when there aren't other sources.

So, manage to keep a garden just with these three things, and you could provide yourself with all you need in terms of protein and starch for the price of only cheap bulk grains like oats, wheat berries, and corn. A bit more space for organic veggies, with their extra nutritional value, and you are most of the way to food self-sufficiency.
Kill and butcher a deer, and you are there - one adult buck or doe weighs at least 100 lbs (45 kg) 'field dressed', meaning the organs have been removed, and the typical calculation is that about half is meat. But those organs are good food! The most nutritious parts of the animal! Freeze the bones for making nutritious tasty stock, turn the organs and some fat into sausages that will store well, and keep the fat on those meat cuts, cuz it's good for ya - 100 lbs of meats, easy, without the hide and other bits that can't be used. That's how it was done in the good ol' days, meaning every day up to about 100 years ago. And remember, there are way too many deer out there, in North America. You'd be doing nature a service.
