Here's another tip for you: Goat's milk products and not just any goats, either. Nigerian Dwarf Goats. They are the cheapest and smallest, yet produce the milk highest in fat. Now why would anyone want higher fat, you may ask? For making butter, cheese, yogurt, cottage cheese, ice cream, that's why! You can buy at least 10 ND Goats for the cost of one Jersey cow. Granted, one Jersey cow will give you 12 gallons of milk a day, whereas a ND Goat will only give you about 1/2 a gallon.
A couple of tips - isolate the billy from the nannies before you start milking them or he will make their milk taste sour/bitter. This is not a myth. Billies are very odiferous and their odor infects the milk taste. You could also eat the billy which might be easier than separating him but make sure you soak his meat in milk to get rid of the odor. I am opting for giving away my billy once all the nannies are bred. Billies are cheap to replace. Anyone who has tried goat's milk on a friend's farm and said they didn't like it probably got it from someone who left the billy with the nannies. You can get milk from goats 10 months out of the year. Next tip - get a cream separator - find one used on eBay or Craigslist because the new ones can be outrageously expensive. The fat globules in goat's milk are so tiny that they won't naturally separate like they will in cow's milk.
Brent, you said you raise chickens? Do you feed them the shells from the eggs that you eat? You should. It will produce stronger egg shells. You can buy commercial laying mash that has the extra calcium for stronger shells, but I just don't trust anything commercial anymore.
