Been gone for 10 days came back and one of my girls has an orange sized mass causing her butt to drag lots of dried waste on her backside. Mass is way lower than her vent. Is it a huge egg or something else all together? Have read about egg bind but can't imagine how that thing could ever move up high enough to come out a vent. Guessing she might be meeting her maker soon. But called the vet and figured I would check here for any thoughts or ideas.
