So I have this dominique hen who is about 2 months old, and her food pouch is extremely huge. I didn't give her a lot of food (and 4 others), but she's a real pig when it comes to eating. She's really wobbly and it doesn't look healthy. Can she over eat? Do I have to seperate her for a while and feed her seperate? Her fellow dominique hens have also had big ones(not nearly as big), but right now she's the only fat one.
