Thanks, Lew, for all the details. I "saw" that farm of yours in the 70s because you described it so well, but I think the back-scratching-grunting comment was the clincher! I'm beginning to understand so much more as I read thread after thread on pigs. It's somewhat daunting, but then I read Kelly's reply (thank you, Kelly), and I think, yeah...2 kunes and she sees no impact yet. Kelly, how long have you had those 2 kunes on your 5 acres? Great suggestion about seeing where the pigs have been when buying them to see how much they've impacted the land. I'll do that.
You also asked how many pigs, and here goes another question. Currently, I buy 50 pounds of pork meat a month, and I'd like to know how many pigs I would need to raise a year to give me that amount of pork? I expect to freeze of course. I'll bet there's some kind of formula, and if anyone can send me there or can give me a ballpark figure, that would be great. I have this vision of keeping 3 -5 pigs at a time, but perhaps that's a bit naive...
Shawn, I appreciate your suggestion. When you mentioned Walter Jeffries the name clicked, and it took me a few seconds..."Isn't he that Sugar Mountain Farm guy?" I asked myself. I'd actually been to his site just before finding this forum, so thanks for suggesting him. At the beginning of any endeavor, there's a lot of sifting to get to know where the good information is to be found, and it's great to be validated that what I'd found actually WAS a good source.
Thanks again, everyone!
