(Is Billy still with us?)
Come on Billy, you got this!!
So, I candled the egg and the air cell is HUGE - I think he may be shrink wrapped. No internal pip that I could see. I am going to go in and see if he’s alive and I might be able to help him get the process started. I’m afraid it might be too late. He also could have died beforehand so I’m just not sure I will update later
I recently had one like this. Somehow, it appeared to be shrink-wrapped a long time ago, as it was all squished up in the bottom of the egg. It seemed fully formed, but I blamed it might have gotten frozen or close to frozen after being laid that caused it. I wasn't sure, so interested to see what you find.
I just don’t know why that particular egg seems to have lost so much moisture at the end. I candled on day 18 and the air cells were large, but not THAT big as when I looked today.
We will bury him later today. I’m sad he didn’t make it, and next hatch maybe I’ll really mark the air cells and watch more closely.
He and Sophie will keep cheering their siblings from above.
Fly free little Billy.
