In that tight of confinement I would be worried the pigs would eat the chickens. They can get along ok if a larger space where the chickens have some room to escape, but it depends on the temperament of the pigs. The pigs will break in and eat any supplemental feed you put out for the chickens and the sheep will get any leftovers. The pigs will also break in to get the eggs. You haven't lived till you have tried to get a 100 pound upside down pig out of the middle of a metal roll out nesting box. It isn't fun for any involved.
The other issue is in a week four pigs even pot bellies (unless they are the super tiny ones) will completely till a 75x75 Bermudagrass plot to bare dirt. Great if you are trying to get rid of it, not so great if you want to hay or graze it later. Also in that time they will have started wallows which will make tractor work rough. I just disced up an acre that I had pigs in for a month and it was scary on the first pass dropping a tire in a 2 foot deep wallow. It took five passes to get it back to sort of smooth so I could reseed it in turnips, radishes, rape, clover, and ryegrass. BTW, Bermuda isn't great for pig food. The mix I just listed is much better. If you can grow it there, add alfalfa too.
