She is no longer eating and her crop is not swelling anymore. She began to chirp a little, I've gave her water through and eye-dropper and tried massaging her crop. She oozes a yellow-yolk-like liquid or foamy-like stuff around her mouth if she moves too much. Wobbly and not walking well. Can anyone give me some advice? She is a chicken house chick that was rescued after the truck dropped off at my neighbors, somehow she escaped and I found her cold and wet, but she has been doing fine until about 3 days ago. Any tips for how to help with a sour crop? My little chicken is only about 12-13 weeks old.
