Two of my six eggs have big "dents" in them as of this morning. The other four look fine, except one has a yellow spot the size of a dime. Is this normal? They were laid August 1, in the morning. The normal looking ones are full and round and perfect looking. The two dented ones feel like if I were to lift them, they would break, so of course I am not going to touch them anymore. They have not gone yellow, and they are all large/the same size. I tried taking photos, but the flash whites out the eggs and you cannot see the denting I speak of.
