I just recently gave 2 dozen fertile eggs to someone... She said she's concerned about them now. She said they are thin and elongated... I have literally had problems cracking them sometimes they are so thick... So I don't know what she means. I also thought that all chickens laid their own shaped egg and there isn't a general shape they're supposed to be. So do these look normal to you? I also have some eggs In the incubator on day 8 that are all developing beautifully all from the same chickens I got her eggs from.
