My boss asked me the other day "What breed of chicken lays a double yolk?", I of course did not make fun of her and let her know that any breed can but it is not desirable, just confused on where that idea will come from.
Growing up we had a "community" fish tank and there was a breed that I think we called "Sword tail", they were orange and the males had a longer black tail fin, like a sword. If the male died a female would change to become a male. This is a very common breed of fish, so since most kids are more likely to grow up with a fish tank not livestock, I can see them thinking a hen may change to a rooster. Still funny though, I would not make the jump to apply reptile and fish biology to avian, but hey, Chickens are dinosaurs so they are a reptile right

I mean all the people my age grew up with Jurassic Park.
Calling myself out here, I was very shocked when I collected my first egg and it was warm

. I have to admit it made me uneasy to my stomach. In all my 3+ decades I ONLY had eggs that were cold. Got over it pretty quick, now I don't even put my eggs in the fridge, but just saying. Not sure what I was thinking, guess I just really never thought about it
