These cows haven't seen sunlight for half a year. Now look how they react when they go outside

Cows are not known to be particularly energetic animals.

Most of the time, they stand still and moo. But these cows are different.

These poor cows did not see the sun for six months, as they were enclosed inside a building to protect them from the freezing winter. When they finally come out.. well, you've never seen cows so happy before..
