The cows mostly eat grass in the fields, but in the winter we have to feed them hay. Every summer we put tons of hay into the loft of the barn so that the cows will have food in the winter. It's very hard work to put all that hay in the barn, but the whole family helps and soon the job is done. Once we found an owl's nest way back in a corner of the hay loft, and there was a baby owl in it. We were careful not to disturb it and didn't bother the nest any more because we didn't want to scare the parents away.
Owls are good to have around a farm because they catch rats and mice.
