Well I now have only one viable robin egg. I was expecting this, and if the last one makes it I'll be thrilled but surprised... anywho, I thought some of you might be curious as I was to see this... WARNING GRAPHIC! Eggtopsy of the deceased robin! There was plenty of yolk still there and the cause of death was clearly a bleed of some sort, right around the chick's chest/stomach (so small) Anyone have an opinion on how many days this had til hatch? *E* Just an FYI, Robins take 12-16 days to hatch.
