Not if you have some trees but if it rains or snows the goats will prefer some sort of shelter to get out of inclement weather conditions.
Goats typically sleep on the ground, particularly in a flat and dry area. Some goats may seek out a soft patch of grass or hay to lie on for added comfort. In colder climates, goats may sleep in a barn or shed with bedding such as straw or wood shavings.
No. Cows are not built to sleep standing up like horses are. Because cows are heavy in the brisket and barrel area, holding all that weight with fat, muscle, four-chambered stomach and other organs, they choose to lay down to sleep instead of remaining standing. They do doze, however when they are standing up, but it is only a light doze, not a sleep.
They may not feel comfortable or safe in there - put some edible straw in as bedding and they might go into their shelter.
