i just talked to the local grocery store and they give produce scraps free to whoever comes to pick up the box. It's usually only a small box but today it was 2 boxes of scraps. What CAN'T I give my chickens and ducks? One of the boxes was half citrus fruits (oranges, grapefruit,lemons,limes) and I thought I had read somewhere they can have oranges but not grapefruit? The other box was a mix of green veggies. I know I wont be feeding them the jalapenos but what else are they not allowed to have? Thanks in advance for the help.
