My 8 baby girl Buff Orpington's are about 7 weeks old. They are in an enclosed run with lots of room. It is mostly dirt now with a little bit of grass. I also have 2 older chickens. I have been feeding the babies everything that I feed the older ones -- bread, broccoli, watermelon, grapes, radish leaves, corn on cob, yogurt -- once or twice a day as a treat. They do have fresh water - inside & outside. They have starter crumbles in their feeder. The older two are fine. The little ones seem to have runny green poop. Will this just correct itself if I stop giving them all of that stuff? I am so worried and feel really stupid. I thought that I was doing something nice for them. I just looked it up on here and found that I should not be giving them anything but yogurt and their feed. Thanks for any help at all.
