Hi all - new to this site and new to chickens. We've got 16 that are 6 weeks old and we're just starting to experiment with foods. Already found they love grass, clover, and grapes, but I'm afraid of giving them something we shouldn't. I have some leftover hampster/mouse food - seeds and pellets. Can they eat that? Seems there are more things they CAN eat than things they can't. Can anybody tell me besides the obvious toxic things what they shouldn't eat? Thank you!
