How is your girl doing? How old is she and what does her diet consist of?

She is now missing. They run around the yard and pond. I feed them starter feed and corn. They all are about 12 weeks. I thinking a fox or a bobcat got her, but know feathers in the yard, pond or woods not sure. if she was sick or not. Do think she will go off in the woods or somewhere to die ?
