Around here, there are few natural trees and thus few windbreaks for cattle.
But that is cured by creating windbreaks with stacks of round bales either two or three layers high. Butted end-to-end, one can create as much windbreak as needed anywhere you want it. Either using junk bales that end up as bedding by springtime, or with good hay bales that the cattle chew on throughout the winter.
By spring calving season, much of the stacks have been eaten or knocked down, and it gives the calves dry bedding areas right up next to the falling-apart bales. The calves stay dry, warm, and out of the wind that way.
The only issue I see is that those bale areas become weed beds the following couple of years because of weed seeds in the bales dropping to the ground.
I would be worried about the upper level toppling over onto da cows.
It would block the wind but concentrate the cows too much for me.
You know the pigs would push around while feeding and step on calves laying nearby.
