Every 20 - 30 seconds a duck will lay an egg. Touch the egg to send it to the nest. In another 20 - 30 seconds the egg will hatch. Rinse and Repeat. (don't actually rinse the egg OR duck because your pc will not work. I speak from experience.)
I'd like to thank my savageness. UUUhhhhh after the duck hatches it goes to the original duck. Sooo yeh. It wasn't me... JK I fixed it the egg always goes to the og duck and I cant be bothered to fix it
