I have just found a broken egg under my broody muscovie duck. the egg white is hard boiled. I took it and broke a bit but there is a duckling in some blooded water that moved a bit. it is day 32. what happened? I guess I killed it but I don't understand why the shell was broken and egg white cooked?! what should I do if I find more eggs like that? I put that egg back and the broody returned to the nest. should I leave that egg there?
