You're welcome. Since she drinks a lot of water, she may be used to that, or trying to break the jam herself. Mix about a 1/2 TBSP of room temperature water with about 1/4 TBSP of vegetable oil and mix it as best you can.
If she'll drink the water or water/oil on her own, give her about a 1/2 TSP to 1 TSP at a time, every hour or so. Let the water work for a few minutes to soften the crop contents, then massage the crop gently by rubbing in circles, gently squeezing from side to side and top to bottom, and moving it side to side. You can also gently "squeegie" the crop from top to bottom to help move the contents downward, but do this sparingly.
If you have a dosing syringe (or regular small syringe), fill it to 1/4 to 1/2ml (same as 1/4 to 1/2 cc), and feed her a few drops at a time. Here's a link that gives a good primer on how to feed chickens liquids:

Coconut Oil is good for Impacted Crop too, you can freeze a few little pea-sized pieces and feed them directly along with a little plain water. You're trying to soften the contents, so they'll empty into the digestive tract on their own. In our experience, the more you can massage the crop, the faster the blockage will break.
