Is the gripe water helping? Sounds like it should from what you described of what it does. Here is some really good information on crop issues. read this then let us know what you think?
I'd def try a poultry feed again is this a female? does she lay eggs? how old? Maybe try making a soupy mash out of the feed and mixing tomatoes chopped up in it. To try and get her started on reg feed again. But for now read this info and don't worry too much about feeding her if her crop is infected or impacted putting more food in it isn't going to help.
