so recently two (I think) of my four duck started laying eggs. (4 days ago) I’ve been getting 2 eggs a day... but one is bigger than the other. I have 1 pekin 1 mallard 2 runners. I believe they are all female. Help me out! Same duck or two different ducks? One is bigger than the other! Lol Thanks everyone for being so supportive of this new duck momma!
