Fulmars only lay one egg. That’s not a surprise when you see the size of the egg compared with the size of the bird. BTO Bird Facts states that the average Fulmar egg weighs 98g, while the adult’s body weight is between 595 and 970g.
That means the chicks start off quite large. See what I mean?
But just because the chicks are big doesn’t mean that the adult isn’t going to go and sit on them to protect them.
