Eggs all weird shaped?

[HerculesChicken]

So wondering why some eggs turn out oddly shaped. Almost like the shell got molded weird? Is the chicken lacking something?

You got a triple yolk? I'm jealous!

I got dozens of doubles from my hens over the years, but I have yet to see a triple. They are very rare!
