Are 100% that she was the deer that bolted across the corn field? It sounds like you were thorough in your tracking though, just wondering if she might have cut right or left.
I think that if the animal was alone when you shot it, it would be more likely to bed down after a few hundred yards. Since it wasn't alone, the others running like mad would only push the wounded one to run alone side them for as long as it possibly could. With that shot placement, I don't doubt she's a thousand yards away.
