One of my hens was squawking so loud today for several hours! She has never done this before, so I thought she might be laying her first egg. I kept checking, but no egg, and I had an appointment to go to. I told my son to check the coop regularly while I was gone and he said he did. However, when I got back from my appointment, there was an egg in the coop! I am guessing it was there for a while because it was warm. It also has a crack/hole in the shell. Is it still good to eat?
