I have a female Mascovy who keeps laying eggs and I'm not sure if I have a male or not. I have 3 ducks and not sure what the other 2 are. I was wondering from the time she lays the egg until the time they hatch, how long until you could see if there was a chick in the egg. I know you can shine a light to the shell and you can see through them and it looks like nothing is inside, how long before you can see if something is in there? Thank you.
Welcome to the Duck Forum! This may help. I am not a hatcher but yinepu is. https://www.backyardchickens.com/a/incubating-and-hatching-muscovy-eggs
