One of my coturnix hens has been eggbound for several days. I keep her indoors, and give her calcium shots and warm bath twice a day, it doesn't help. She just sits there, fluffed up in a ball, like a kiwi. Drinks very little, barely eats, unless I give her mealworms - then she comes back to life briefly, devours the mealworms, and then sits again. The problem is, she doesn't seem to make any effort to pass the egg. I tried to put mineral oil in her vent, and massage her carefully. She totally freaks out screams and fights me, but no movement in the vent. Is there anything else a novice can do to help? (I won't attempt to break and extract the egg, no way I can do it right). Is there any chance that she will pass the egg eventually, and when I should draw the line and cull the bird?
