Used, old riding mower.
Or an old fashioned manual scythe. Good for grass and some mixed weeds.
There's also push mowers, the manual ones, where it's human propelled. I have one of those, too. Those are best for clean lawns and cut regularly! Too tall or steamy weeds and it's screwed.
Hogs have a very similar stench as people have, the BO & the poop. You can potty train pigs, not all of them, not easily, but you can.
You might have to bribe the neighbors to keep the peace. With chicken meat or eggs.
Buy a lot of garden hose and hook it up to a sink to water them. I do this in winter. You can buy a 300+ gallon trough, fill it and use that water to bucket out to the others.
Sell off the geese, you can buy new ones later.
Same with the chickens. Both are cheap to restart later on.
She's got a personality of a more wild type of rabbit. She's also maturing and they get more witchy as the go through that, like a teenager.
Rabbits also don't like sudden drastic changes and being out in the open. That would explain some of her freak outs.
If you don't want to deal with that...
I had 2×3in welded wire over a chicken run. And heavy duty tarp over top, wood to hold it up and drain.
That has lasted 10+ years, new tarp every 2yrs, swept the snow off as it built up.
Had rabbits on grass, they'll kill it all off and you'll be left with dirt/mud. Water will seep down into...
They're going to be eaten.
You need wire on the bottom, 1/2×1 inch wire on the walls and 1×1 inch wire on the roof. Or do solid roof. At least 1.5ft should be tiny hole wire or use solid wood. Higher can be larger, but foxes, weasles, rats can get in.
No solid roof means soggy rabbits. Soggy...
Check your local FB horse groups to find recommended trainers.
If she's fat n out of shape, best to get her slm and ready for the saddle training first, or they may charge you a month's work where all they do is get her thin.
Have you had horses before, trained them or done basic ground work?
