Thank the gods there is someone else out there with freak of nature birds! I have six 8 week old chicks and at LEAST two of them are already laying. I don't have the foggiest clue HOW they're doing it, but they are. Two of the chicks are americaunas, so I know it's not them, then we have two RIRs and two SL Wyandottes. My best guess is that they're from the Reds.

The one on top is from one of my older hens. She is the only mature hen we have that lays tan eggs, and I KNOW she did not pop out any more than two eggs in one day. The little eggs are even exactly where the chicks nest inside the coop. Like I said, I'm pretty sure it's the Reds, but regardless, I'm putting a **** nannycam in there. >.>
(And no, they are not wind eggs, trust me, so don't even bother offering that up as an explanation.)
