My pekin ducks share a coop with the chickens and we've been getting a large white egg everyday for the last couple of days. I wasnt sure if they are duck or chicken eggs but today im pretty sure they are duck eggs. I already put 3 eggs in the fridge and i would like to know if its too late to incubate them myself. I want to leave the new eggs in the coop with hopes of hatching ducklings. This is our first experience with duck eggs and hatching. Any advice appreciated.
