I have an egg should be on day 18/19 I THINK. It was under the hen and she had been stealing eggs. I locked her up a week ago with her nest. I took the egg and candled it....and had been keeping an eye on it for a while because it looked like two yolks in it. Well, now there is liquid in the air cell when tilted...couldn't see movement till just a minute ago. Embryo seems way smaller than 18 or 19 days. Is this egg doomed? Has anyone experienced this?
