Can I eat an egg from my chicken that was frozen?

When I let the chickens out this a.m. I found an egg that I missed from yesterday. The temp got down to 6 degrees last night and it was frozen (but not cracked). I let it thaw out on the counter and scrambled it. It was delish, no problem eating an egg that was frozen as long as it's not cracked open.
   Definitely discard any cracked eggs because bacteria can enter, it's not worth the possibility of getting sick.
