Strange new egg in the coop today.

[SharkmanDan]

We have 21 reasonably mature chickens, in our coop. Three roosters, one frizzle (pullet) and one Polish (pullet). The remaining 16 range in age from 5-1/2, to 14 months of age. We had been getting a consistent average of 8+ eggs a day, out of them, ranging in size from the small side of medium, to pretty jumbo. Only one hen is laying white eggs, as best we can tell. That's our Brown Leghorn, Mrs. Brown.
Today, we found this tiny egg, in the henhouse, and our gray/white Polish, had been acting a bit more docile, than usual. She's typically very friendly, and gets along well with my grandkids, and loves to be handled. The past few days, she's been fairly sedentary. Just didn't seem to have much "Get up and go". I'm thinking it is the first egg, from either the black frizzle, or, more likely, the gray and white Polish.
Can anyone here, help me decide which this egg most likely came from?

its a 'torpedo' egg. I had an easter egger who laid double yoke eggs that looked like that frequently. If they are fertile I wouldn't recommend trying to hatch it if it does candle as twins. Twins usually don't make it.

:Actually, when I went to candle it, it was so small, that I dropped it down the paper towel tube, and it cracked on the lens of the LED light. The membrane was obviously compromised, so I decided to just crack it open and see if it was worthy of cooking. Sure enough, it was all albumen. No yolk. So, I cooked it, and we tasted it. It tasted just like any other egg white. No difference.
Anyway, I'm still not sure who laid it, but figured by it's size it likely belonged to one of the two smallest and youngest birds. Guess I'll never really know.

In my memory the only time I have ever gotten an egg like that is from an old hen ending her egg laying career, I could count on 2 or 3 each week... Do you have older hens?

I'd be careful...if one of your hens is beginning to lay misshapen or malformed eggs, she could be at risk of becoming eggbound. Keep a close eye on your chickies!

It is a fart egg or wind egg...just a mistake. Not a big deal, and common in new layers. Polish lay white eggs.

Ok, thanks. I'm new to chickens, and not familiar with the nomenclature. But, the "fart" egg sounds about right. It was not in a nesting box, it was on the floor of the coop. And, none of our birds are over 14 months old.
