Mine LOVE weeds of any kind (well of the kinds we have). We have dandelion, cow thistle, spiny lettuce, mallow, and grass weeds - the grass type ones or lawn clippings are one of their favorites! They also get some scratch and flax seed once a day and love that! They also love grape leaves
Mine love any table scraps or leftovers out of the fridge. Veggie garden scraps too. I feed them cereal sometimes too. They love cereal! Fresh out of the box, just throw it down and its gone! Sometimes I can't even get it that far. If my red rooster figures it out before anyone else does, he will start jumping for it and sometimes ends up on my lap.
