I have 15 hens that are about 6 months old. Most have been laying for a couple weeks now. I was quite suprized and let out a few expleives when I saw this HUGE thing in a nest box! I think its from my huge black Australorp I have, the poor girl! I had it weighed and it is 85 grams. A jumbo egg is 71 grams. Not quite Guiness material but I am very proud!
