Jumbo egg layers

[HBuehler]

white leghorns you will get xl to jumbo eggs every day and they are single yolks.I even have a broody one

We do weigh our eggs and the Australorp,Delaware,Rocks,Sex links and Orpingtons all lay on the large side of large to XL with an occasional true jumbo as a breed but there are some individual hens in all of our breeds that lay jumbos as a normal. We won't keep a chicken here very long if it won't lay at least on the large side of large other than our bantams

My limited experience says red star sex link and turkens layed the biggest in my flocks. I also found that the former birds have a layed back personality which I appreciate.

I have 5 RIR and a Gold-Laced Polish that lay consistantly eggs no smaller than 2.8. They do not fit in jumbo cartons. They are consistant layers and people drive 20 miles to get them. I have to take reservations for these eggs. I've had Australopes and White Rocks and Black Giants and you name it and these birds are just awesome.

Maybe it just depends on the care that their owners are giving them or their own genetics. I think a bird of any breed will come along and occasionally surprise everyone.

The world record holder (not sure if that's the official current record) is a Red Shaver chicken (a breed recently recognized as developed in Canada - Ontario I think?) with an egg that weighed 143 grams. A Jumbo egg being 65 grams, this one was HUGE! Here's a link:

My white girls are shaver/leghorns - my biggest egg was 92 grams.

ETA: This article calls jumbo 70 grams, I was using the numbers on my jumbo egg cartons.
