Sorry I don't have a pic to post tonight of the egg. My ducks have been laying since Sept 19. We have 5 females and get 3 eggs a day. We've had two double yolkers and all the other eggs have been about 70 grams in size and had a hard shell and were oval. For the past two days one of the ducks has been laying eggs that are kind of round with one or two sides that are flat. We have no ideas which one is laying those eggs. The eggs are small but really, really oddly shaped. I'm concerned but I'm not sure I know if I need to be?!?! Could this be an injury or an indication of another problem? Any ideas?
