One of my chickens laid an egg in the outdoor part of the coop yesterday. It didn't look like the eggs I get from the elder hens, plus the elder hens ALWAYS lay in the nests! I have a bunch of young australorps, the two older ones being approximately 12 weeks old. Is it possible that this egg came from one of them? What's the earliest that any chicken has started laying? I see 14 weeks being not unheard of, but 12?
