Kate talks to Amy Chapple about Redwoods Farm in Devon, where she has laying hens that roost in converted livestock trailers and her parents have broilers that live in 'chicken tractors' or polytunnels. They all get moved around the farm, following the cattle and sheep, scratching up the dung and keeping their active minds busy. Their chickens are fed on a soya-free diet with most of the feed being grown less than 10 miles from the farm.
