I buy free-range eggs from the lady acrooss the road (delicious btw). A few weeks ago I cracked one to find it had three yolks and today she has told me about one with four! Also she has had two sets of identical twin chicks. I didn't realise that you could get two chickens in one shell and have never heard of more than a double yolked egg. Any one know any more weird facts about chickens?
