I can tell there is an egg in my chicken and she is unable to pass it. I have used the many ideas on the internet, but when I feel inside of the chicken, I feel as though I am not feeling egg shell, but it feels like some kind of softer tissue is between my finger and the egg. Could that be the actual egg, or might there be more of a problem. We have soaked her in a warm bath, which she loves, and put mineral oil in the vent. Any other suggestions?
