My guinea eggs are here! Ok, now I know not to wash them but how do you clean the mud and poo off of them? Should I just gently rub them with a paper towel or rag? And I am not finding anything specific about humidity level. What should I start with? It's about 43% right now. My eggs need to sit about 8 hours before I put them in the bator. All 36 eggs look fine. Here we go!
