I've been working with her on this for about 5 days or so. It started with her moving her neck in strange ways. I had put hay in as bedding and since then replaced it, thinking she blocked from that. im wondering if she has over done it with oyster shells. i dont feel any hay in her crop, just grit feeling. She is a new hen that we got as lay hens. Her crop is soft and feels like its full of grit or broken up oyster shells. She was eating it seemed a lot of oyster shells. She's had bad diareha, watery and green. I have made her vomit a few times, a bit of grit looking and some grains. not a lot. I treated her for worms and she has passed 1/2 inch worms, yesterday evening. She hasn't pooped at all last night. I felt her crop this morning and its about the size of a golf ball and a feeling of squishy and with grit. I'm getting frustrated. She was so vibrant with energy, I'm worried were not getting anywhere. She doesn't really smell like sour crop. Last night her crop felt more of a normal feeling with grit. I have been giving her yogurt, boiled egg yolk, cedar vinegar, and olive oil three times. I have also been messaging her crop. She is starting to stretch her head up with her beak opening up.
