One thing I always see missing on these threads are chickens.
Just a couple will provide a few eggs a week most of the year. Having fresh eggs (which need no refrigeration) added to your diet would be a great thing in tough times. Chickens can forage on their on and eat most human food scraps. Eggs would be good to barter with. Can always just eat the chicken if needed. Two chickens particularly a smaller breed could even be included in a “bug out kit”. If you are trying to be somewhere unnoticed then no roster, but if that is not an issue, then they are not that hard to raise, one hen sitting on a half dozen eggs, even if only 2 or 3 hatch gets you ahead of the game
not in northern climes they cannot forage.
they require feed and feed is expensive
Road Island reds will easily make it through Wisconsin Winters and lay as many eggs as a leghorn. Plus the long males can stew up pretty well.
When you think about it, fresh eggs are a nutritional 'protein bomb' which gives you protein, and fats in one efficient tiny package that comes already wrapped.
Chickens which are laying eggs age, are photo-sensitive and may need supplemental lighting in Northern climes, and definitely in winter.
Honey serves as a sugar substitute, as well as an medical antibiotic. Also, garlic is said to have antiviral properties
