Hello everyone-- this is my first post here ever!! i've been enjoying reading everyone's posts and now have some questions. i have 12 chickens penned, and sometimes free ranging. i love to give them all my scraps & huge clumps of weeds, etc from the garden to eat, as they are not usually allowed to free range (we live next to a walking -dog- trail) Is there any foods that i should NOT give my hens?? thanks you!
