I forgot you give an update before I left last night! I was tired. What I found was quite interesting, and maybe one of you can tell me if you've seen this! But before I begin, let me just tell you that the duck is STILL in the egg, but also still alive (and also quite vocal about the fact that he no longer wants to be in there)!
So, let me begin the tale.... I opened up the air cell with a little view hole, which soon turned into a rather large view hole, because I couldn't figure out what I was looking at. Once it was opened, I could see that what I thought was his beak when I was candling, was actually his knee (?) sticking up into the air cell, and it had broken through the inner membrane! I don't know how it had happened, but there was dried blood around that area, but not actively bleeding. The problem then became that without the hard shell as a barrier, he kept trying to push his leg out more, causing it to bleed. I quickly devised a plan to take sterile gauze, pack it into the hole, and tape it in place. That seemed to solve that problem! Now the problem became finding his beak, which actually wasn't very hard, because I had already suspected a a failed pip at the other end of the egg, but thought I must be wrong since I saw his "beak" in the air cell. So I then made a small view hole there, and there he was! I dampened the membrane, and I saw that there were still a lot of blood vessels, so I put him back. A few hours later, I checked and there were still some blood vessels, so this is when I went home for the night.
When I came in this morning, I was happy to find him very chirpy and angry. I checked for blood vessels in the membrane in the air cell, and I didn't see any, so I cleared a little more around where his head was. As I was doing that, I noticed there were still some spots of larger vessels... so here I am... still waiting.
Here is a picture of what it looks like right now. What do you all think?
