Her beak has been pale lately compared to my other pekins then it started to develop dark spots and now you can see the flesh underneath. She seems to be energetic and acting okay but is smaller than the other females. Any ideas what could be wrong or what I can do for her? She's about 4 months old. I'm afraid it could be malnutrition due to treating them with lettuce too much? The others all look fine. Please help!
