I just crawled under my house and found a ton of chicken eggs my girls have been laying for goodness knows how long. I tried putting them in water and they all sank and lay flat on the bottom. Is the float test super reliable? I don't even know how long they have been laying under there. Maybe days, maybe weeks, maybe months! The have always liked to hang out under there and I've had them for a couple of years. I'm scared to crack any open.
