I have a six year old bantam hen that is egg Bound. You can feel the Egg in her abdomen it is hard. I have soaked her several times in warm water. Used Vaseline and mineral oil on the vent and massaged her abdomen like pinching cheekes of a baby. I did an internal exam and felt as far as I could and could not feel the actual surface of the shell. I hAve given her calcium as well. Any ideas?? I found herand started treatment at 9pm yesterday. Thanks for any ideas!
