If a duck starting laying eggs on May21, 2016 and laid an egg a day for 19 days and the first 6 were not fertile (not sure, they went bad) trying to hatch them. Should I attempt to try to hatch the remaining 12 eggs? She is a pekin duck surrounded by 4 Mallards and 1 large male (I think) white goose that stay together all the time. Would it be possible that the remaining eggs have been fertilized or once she starts laying,..could they be fertilized somewhere along the process? Or chances are the remaining 12 are not fertilized?
