How to fatten up a scrawny hen? She individually used to have a lot more meat on her keel bone. She's a very big australorp/orpington. I have food and water in more than one location, so although I figure bullying's involved, i feel like she ought to be able to eat enough. They eat layena omega3 layer feed. Ia there something high calorie to give her to quickly put some weight back on her? Poor thing, she's molting and it's cold out and she's so skinny. It's not just my perception. She is downright scrawny for herself.
