I have a Bielefelder female that hatched yesterday and had some problems with its abdomen/navel not being completely healed. I separated it into a little ICU unit it’s abdomen appears to be healing well however I checked it’s vent this morning see there’s just a pinhole opening. Has anybody experienced this? Did it resolve itself? I’m wondering if this chick is a lost cause and I should go ahead and call it sooner rather than later. It’s absolutely beautiful and larger in size and most of the other chicks.
