We have a few eggs that are full of fluid after the due hatching time and clearly won't produce any DLT's. My wife took two intending to boil them. One remains in the water and she must have eaten the other before going off to town. I suppose that if I don't get a call from the hospital the egg was OK to eat but after 28 days and more in the heat out there I have my doubts. What is the general rule, please, for eating non-hatching eggs? Are they safe for me to eat or should I keep them until I have a visitor for tea who outstays his welcome?
