MIne get veggie peelings although I cook potato peel for them, the rest they tend to have raw. they have their own shells cooked and fed back to them. they have cooked pasta, rice, sweetcorn, jacket potato skins, yorkshire puddings, porrige when its cold out adn when we have a milking nanny on site they get a bowl of goats milk too.
Of course they aren't supposed to have any of the above that has been prepared in a kitchen that also handles meat. we have very little meat as hubby is a vegemetarian and the children are funny about chewy meat (little toads) but hey ho. so yes, there is sometimes meat in my kitchen but the chickens don't eat it, ever.
DEFRA have a lot of info about what we shouldn't feed on their website. x
