Long story short, I found a Muskovy duck egg on the pavement and took it home after the mother rejected it. The egg has been doing great for about three days now in my homemade incubator; wiggling, growing etc. My problem is that I believe she may be a twin egg or double yolker. I can provide pictures, but upon candling this morning the egg seem to have two different tiny lifeforms. They wiggled around pretty independently, but I could possibly be seeing the body and head as one of the blobs was darker than the other ( even though I'm sure the neck could NOT stretch as far as to seemingly separate the blobs)? Any advice? I am very new to hatching eggs; I have never done it before, though I have loved birds for my whole life. thank you for the help!
