I have brown chickens who produced mostly brown eggs, 85% of all eggs sold in UK are brown, this change will result in millions of hens being put down, the majority of white eggs will then be imported with all that carbon involved in transport, from places where hen welfare is not a patch on UK, once again Farmers being crapped on by daft #NetZero while UK congratulates itself, but is importing all products from places that don't give a second thought about #NetZero but we can take the morale position while we punish our economy and Farmers! @JeremyClarkson
