My 10 month old buff Orpington looks and acts like she's in tip top shape but when I pick her up she feels like she's all feathers. Her breast bone is prominent and she hardly has any meat on her bones. My two girls live in the city and due to the season (getting dark early) and my schedule I'm only able to let them on on the weekends. They go through their food fairly fast and when they are out they are great foragers. She's obsessive about her worms. Is this just the nature of her breed? Or could it be worms or parasites or something? I've never wormed them... should I? Is there anything natural that would work for that? Thank you! Stephanie oh, and she lays 4-6 eggs a week.
