Your ditch area sounds like the 3 acres we bought in FL....I thought I'd ever get that place even close to cleaned up, but had a similar plan to the one ya have there and after about a year we got it in decent shape....still had some to do, but didn't have to push so much to finish it up. We never did find anything very useful....but, did uncover a few scorpion nests....
We rounded up the two sheep that Jay wants but I'm betting that one of them (Wild Thing) isn't bred yet and she is still standing for the ram. We have them in the sorting pen until tomorrow so I can talk to his Grandfather to see what he wants to do. I'll let him choose another that is showing with lamb now or leave her here longer. He's getting antsy but I won't let him take the one ewe by herself.
We wound up trimming her hooves without the tilt table since somehow she got turned upside down in it.
A couple of yrs ago I saw a youtube video of a piece of equipment being used to flip the sheep upside down to trim hooves....I believe it was in Austrailia or New Zealand that it was being used in....boy those guys were extremely fast at trimming too. I thought it was pretty unusual, but they did goats that way, too.
We have friends that have a chair like thing Premier calls a deck chair but it isn't easy to get some of the heavier sheep in it. Most of ours are in the 140-170 lb range and they aren't that easy to flip into it. They are fairly easy to keep in place as long as you have two people and none of them are that afraid of me so they don't panic.
Australians got it goin' on when it comes to sheep care!
We have done a lot of cleanup on our place too. We are at the point, that as long as we don't dig any holes (thus turning up more "artifacts") it is pretty clean and picked up around here.
@Latestarter you have a "mystery mobile" in your woods across the creek or is in your big ditch? Did you finally go across the creek to investigate? Oughta be fun getting that out of there.
I've seen pictures of that chair, looks like I'd end up in it instead of the sheep.
