This is a great reply. Another thing that can cause a blockage is a stuck egg or tumor. Get yourself some KY Jelly and latex glove and perform an exam.Hi,
After reading your post it seems she is blocked. Hay or even mulch hay is not the best bedding. Pine shavings are the best and DO NOT use cedar. The grit or oyster shells are ok in limited amounts. Should only need about a tablespoon full per 5 lbs. of feed. Water is the key. The cropo will not empty anything without water. They do not need a 24/7 supply of store bought feed but they do need a 24/7 supply of water. They can have greens in their diet such as small grass clippings and dandelion greens. I would offer water and lay off the feed until the crop is cleaned out.
