No bother with the questions!
The brown color is due to the length of time the gunk hadn't moved out of her crop. It's still possible she has a blockage somewhere in her intestines.
Can you cage her for a few days? She needs to be on a soft diet, no free ranging or hard seeds. Dampen the chick feed to so it's easier to digest. Check her poop carefully and let us know what it looks like. Vomit her very carefully so as not to aspirate and only first thing in the morning so she can absorb food and water.
Plain Greek yogurt is fine. If you have any Apple Cider Vinegar you might mix a 3/4 teaspoon of it into a quart waterer. It will help sour up the intestinal tract and prevent yeast from growing further on down from the crop.
