I had one of the babies from this last clutch develop a "blister" on the top of it's head. I last saw it's head a few days ago sitting on top of the cut egg. Then yesterday everyone else was either out or making their way out this guy still hadn't popped his sack. So I checked to see if it was alive, it moved around just fine but had this "blister" now that wasn't there a few days ago. Everything went normal with this clutch and they were cut on day 53 and it's around day 60. The only odd part to this egg was that it was a boob egg and what was inside on the bottom. Has anyone ever seen anything like this?
