The amount of fodder stored thru the winter for the livestock is gonna be huge. My most conservative estimate for the cattle is 150 tons. Yes, 150 TONS. Fodder-silo's and barns are going to be another construction project for the colonists.
To save some construction, may I suggest pit silos. We had three of these when we had a lot of cattle. Basically it's a long trench maybe 30 feet wide by 100 or more feet long, and about 6 or 7 foot deep. At one end it is slanted up so you can drive in, and the bottom end is open so you can drive out. This means it's best to be built on ground that is slanted.
We would drive though pulling a wagon and dump the fresh cut hay or chopped corn. Another tractor would level out the hay or corn and drive over it to compress it. Eventually you would fill the entire trench or silo with feed. Later you could access the pit silo from the lower or open end to take out feed for the cattle.
The only thing you would really need is a concrete bottom.
After we got rid on most of the cattle and only used one of the pit silos, I turned the closest one to the house into a singles tennis court.
