My children have neither learnt their table manners nor eat everything we put in their plates yet. I wonder if it's ok to give their leftovers to four week old chickens. The turnt down food includes soups, milk, meat, bread, cooked grains (rice, barley, quinoa), eggs. Is there anything I should be mindful of making sure the chickens don't get? Some of our food maybe salty, spicy, oily.
