Wow, 6 months?! Why? Supply is pretty continuous, can keep them pretty much anywhere (even if there was just one county in one state suitable for rearing hens.. you could post them to any other faster than that?), what introduces such delay?
Price stability requires a stockpile - there are egg warehouses dotted around the US, and they exist pretty much solely to ensure a regular supply and therefore predictable price of a very fundamental foodstuff.
