Thanks for the apple N. Neta. Yep, I posted to this thread to inspire others to start NOW at whatever age they may be. Don't put it off, 'cause it gets harder the older you are. When I was young, strong, and energetic, I wasted my life sitting behind a desk for 40+ years and my only exercise was hiking, skiing, or cycling on weekends, when I should have been doing what I'm doing now.
I struggle to do the heavy work at 75, but I do what I can every day even if it is only a couple of hours of work, and though I'm not progressing as fast as I would have at 25 or even 55, I am seeing improvements to my homestead every month and learning skills that make me more and more self-reliant. I was never mechanically inclined, but now I can maintain and repair my tractor, riding mower, and water pumps, etc., and I may take a welding course soon as I see a lot of ways that skill would be useful.
Got my PDC last winter online with Tom Kendall, a protege of Geoff Lawton, in Australia and used about 10 acres of my land as my final design project. Still building infrastructure, mowing and sowing to improve pasture, cut one swale so far across the slope and started a food forest with 5 fruit trees, two varieties each of grapes and blueberries, still repairing barn and sheds, and the mobile home that was gutted when I bought the place is now quite livable. Still need to replace 8 windows, install finish flooring, and install 2nd bathroom fixtures.
My 7 hens and 1 rooster are fat and happy, especially when the dog is tied up and I can let them free range. My Aussie Shepherd pup is a failure as a LGD, and though he does keep other predators at bay and the deer out of the garden, he is himself a predator when it comes to poultry. He doesn't eat them, but he thinks they are toys for him exclusively. Though he wouldn't let any other animals or birds of prey harm them, he loves to chase, catch, and play keep-away with them, toss them and catch them again. I've been able to rescue several of them, but I'm not fast enough on my feet to catch him, so I have to divert his attention to some other object like a stick or ball while I pick up the traumatized chicken. A few have had heart attacks and died of fright. I should have gotten rid of the dog after he got the first chick, but he is so lovable most of the time, that I kept giving him reprieves. Now I'm trying to rehome him with a family that doesn't have poultry.
Tried pigs last year with a pair of piglets from different parents. They grew up trained to electric fencing, had a small litter of piglets of their own which I sold for enough to cover a year's feed, but every time the power went off, the boar would head right for the dog house, evict the pup, eat his food and bed down in his house. He was also very destructive, crushing trash barrels and knocking the front porch posts out from under the corners. Sold the sow, but the boar is still either penned up or stalled to keep my dog from attacking him now that he is big enough to take revenge. Always something to keep my adrenaline pumping.
Homesteading is a lot of work, but enjoyable work with many rewards. The first younger family I brought in to share the land and the labor turned out to be duds, and I had to evict them, but I may try again with one or two singles. Plenty of land and plenty of projects to work on. No loafers or parasites though.
