Are you still treating for sour crop? I've got a hen that I am really struggling with. She's had diarrhea and is so skinny. She's also molting. I fear she has a slight impaction, if that's a thing. There is some movement in her digestive tract, but her crop will not clear. I've done the molasses flush a couple of days ago but I believe I'm going to try it again and if nothing, I'll start massages many times each day with oil. She's got to get some weight back on and absorb some nutrients and minerals. I'll probably start a thread on her.
