Hubby built some ~10x12' chicken shelters on wheels and put a *lot* of effort into keeping them as light as possible, and as a card carrying 115 lb wimp, I can only move them if they're heading down at least a slight slope. To move them effectively, Hubby actually lifts up on the front slightly so he's helping it skid overtop of the grass. Tall spring grass is a major obstacle.
That's a pretty big structure for 2+ sheep... I thought about buying 1, possibly 2 of the 10x10 dog runs and linking them together on skids. Any other ideas?
Someone I know tried to build similar out of cattle panels. The big issue is that flat land is generally not flat. Without coming up with some sort of easy to connect system to accommodate slope and uneven ground, even a modular system was too time consuming to be effective.
What about portable water? I'm not big and strong, so even a full 50gal barrel might be too much for me to pull myself.
I did build a skid to hold a stock tank for my ducks and geese. Even on decent wheels, I couldn't move it full of water. I would dump the water, rinse the tank, move the skid, then refill the tank from a hose.
Over the last 25 years, I've met many "portable chicken coop/runs". Very few of them ended up being moved daily or even every second day. At least 1 one coop on wheels was placed inside a large fenced area and then the coop was pulled by hand every 2-3 days to distribute the night droppings (it had a wire base), and the birds free-ranged during the day.
The issue of "what to do with the sheep while I'm moving their pen" is a *very* real issue, as is your concern about predators. Livestock guardian dogs is a common answer here on permies. People who have never seen certain predators near their land suddenly discover that the livestock they bought is a strong attractant.
Some sort of more permanent paddock/shift system with a small central hub for managing food and water needs has much to be said for it. Traditional management involved a constantly present "shepherd" to keep the flock moving and herd them to a safe place to bed down each night.
