We had two eggs under one of our pairs and the first egg hatched two days ago.... This morning I decided to candle the other egg in the nest since it's sibling hatched two days ago. I candled the egg I saw right away that it had died a day or two before, so I cracked it open and the first thing I saw was two heads right by the air sack and both beaks were pointing down. I couldn't believe that WE had twins! The day before I ever even saw this egg I just happened to be reading about twin pigeons, but never thought it would actually happen to us. I'm VERY sad they didn't make it out, I even heard one of them pecking at the shell on the day their sibling hatched... Has anyone else had this happen with pigeons?
