What the Eggs!

I bought a brand new carton of eggs. One of them had translucent polkadots. This morning I went to go separate the egg whites but after cracking it open it, the egg white was murky. I thought I might've been sold some rotten eggs so I picked up the bowl and leaned over to smell it. THEN IT SQUAWKED AT ME!! WTF!!!! I screamed at the top of my lungs and threw it in the sink. I think it might've been gas build up in the egg, or air pockets, or it could've been a half baby bird all ready to hatch. It's now in the garbage disposal. I hope it doesn't crawl out. I'm done with eggs, or at least cooking them.
