Multiple animal types in one barn?

We are looking at homes to buy, and one has a lovely barn that is all one room. No stalls or any partitions.
I would love to use it for  a few small goats, chickens, and ducks.  Maybe a pair of geese.
We will use electronetting to rotationally graze them around the property, but bring them back to the barn at night.
What would be the best way to partition it for all types of animals to be happy, without having any prior building skills?
Links to photos of people using a barn in such a way  would be great.

Have you search, multiple species barn layout?

Around here, people really like hog panels. Though if you have weasels, the large mesh won't protect the poultry.

Also, secondary question….
Does anyone have wooden floors in their barn? Best way to protect them?
