We started with 18 eggs, 4 of them where not fertile, 1 grew bacteria, 1 was an early loss. So at the 2 week mark we where down to 12 eggs. 8 of them hatched over 4 days and the last 4 never did hatch. We hope to try again and get a better percent. Having the ducklings around was wonderful and we miss them. We took them back to the farm as we intended to after a week with most and 2 weeks with two of them. What an adventure!
