'They look the same, they taste the same'
Many of the UK's hen farmers have started to label their eggs, explaining that their "free-range" flocks are being kept in barns for health reasons.
The government ordered farmers to put all free-range hens indoors in December, to guard against bird flu. The order was lifted on Tuesday, but many farmers, including Toby Rush from Rymer Farm in East Anglia, will continue to keep their birds indoors.
Mr Rush tells the BBC's Emma Simpson why he is doing so.
