I am refering to the hole that the egg comes out of. It is the same hole that chickens poop and pee from. It all comes from the same place. I was around 25 years old when I learned it and this is how I found it out.
I was at my sister-in-law, Jeannie's, house. She had a chicken coop out back. I decided that I wanted to fry up a good fresh egg. I went out to the chicken coop and there was an egg in the middle of a nest just like it was supposed to be. To my surprise it was covered in goop, by the word "goop", I mean excrement. I had never seen an actual egg in it's natural state and I was quite surprised by this.
I took the egg to the house where Bobby told me that is how all eggs come out, even so I was quite disgusted by it. He said just to wash it off and fry it. Skeptically I did as he said. I washed the egg and then I proceeded to fry it. I then took it to the table and sat downwhere I immediately decided that I couldn't eat such a thing. I gave it to Bobby.
I went over to the fridge and took out an egg which had come from the store. I fried it up and I ate it and I was as happy as a clam!
I know it shouldn't have made a difference to me, but it did.
