‘They don’t belong in a concrete shed’ – cows still happiest outside

While modern indoor farms aim to recreate outdoor life minus its hazards, scientists say having a choice may be best for animals' wellbeing

It's springtime in the UK and hundreds of thousands of cows are being let outside for the first time since the onset of winter. Social media is full of videos of the animals joyfully jumping and galloping as they rush through farm gates into grassy fields.

After spending the past few winter months sheltering from the cold and rain in our barn, this joyful moment signifies warmer times ahead as we move into spring.Look at them go! pic.twitter.com/xhyoSlb1yP
