It's springtime on the farm and the focus is on sheep. We follow the first 12 weeks of a lamb's life on a Welsh Hill farm. Along the way we find out that sheep are highly social animals.

It's summer and we follow the first twelve weeks of a Hereford calf'ss life as he makes friends and settles into the herd. We discover that cows are much more than mother nature's muck-spreaders.

It's harvest season. We follow a litter of piglets from birth as they grow up in the Brecon Beacons. We test the theory that every piglet always returns to the same teat to suckle.
