My hens just started laying the beginning of August, (I'm a newbie) I only have two, so for the most part I get two eggs a day. Today while they were roaming around I found a hatched egg, but the shell wasn't hard, it was a white almost plastic lining of sorts. It was a perfectly pretty egg, looks like she meant to poop, but the egg came out instead! Anyone know what this is or why it happened?
