I have seen online that some people wash the eggs before they put them in the incubator to take any bacteria off the egg and my mom said that there is a film on the egg to protect it but seeing as how our hens use the nest boxes as bathrooms i thought it would be wise if i start washing them i mean they aren't growing any embryos yet so it shouldn't hurt them right? I was just going to wash them in plain water but my mom started thinking maybe we should use an all natural egg wash on them any suggestions would be helpful
