Not the first. I found it in the wood chips under the roost. From the same size chickens as the large brown one. The only thing that came to mind was it might have been laid by a Buff Orp I have in full molt. She is a scroungy looking site.
The big brown one is from a Buff Orp. The white one is from a OEG Bantam. The little brown one had to have come from a Buff Orp or a Black Australorp. Never seen one this small before.
