I decided to try candling my welsummer eggs again this evening... I am on day 13... What I am seeing in almost all my eggs is one very large "blob" at the end of the egg. I can see in 4 of them a dark black circle which I am assuming is thier eye. I have a few that have no blob at all and assume they are no good. Are the blobs good or bad things??? Tried taking some photos but they are no good at all....can see nothing at all in the photos.
