I noticed lately that my Wyandotte, Ani, has a really big crop. I didn't think anything of it at first, but then the last time I held her, she felt thin (as compared to usual, but not dangerously so. Believe me, Ani had plenty in reserve). I believe she is crop bound. I checked her breath and it doesn't smell sour. She is behaving totally normally, eating and drinking, but her crop is really big and squishy, and it isn't shrinking overnight like it should. I had a hen with a full-blown sour crop about a year ago. I inverted her and encouraged her to regurgitate all the liquid in her crop, and then I kept her on water and olive-oil-coated scrambled eggs. I tried to get Ani to regurgitate this morning and even though her crop feels like it's mostly water, nothing came out. She got a nice, long crop massage, but it didn't feel like much was happening. I have her separated without food or water right now. Should I give her water with olive oil mixed in it and see if that helps her? Any other advice is welcome!
