I have a single white silkie who is about 14/15 weeks old, and she's getting very skinny! I was thinking its because she's alone (her sisters are still too little for full-time cohabitation). She eats, but not near as voraciously as the BR and GLP. She's all keel, you can see the prominent ridge through her poofy feathers. What can I do? Is there like, hi-fat chicken protein shake or something???? I love her to death, she's great... I want to be sure she's not gonna kick the bucket!
