They seem HUGE for pullet eggs but jeez louise- just looking through this thread it looks like EE's tend to lay a large first egg? Has anyone else found this to be the case? My other girls laid 2/3 size eggs to start.
Yep! Andromeda gave us a double yolk XL her first time. She has since backed down to a more reasonable (*) Large.
Echo is an Australorp. she started with a Medium-Large and is now at a Large-Medium a week later.
All the other breeds started small. The Anconas both started with a Medium (I would guess). Each laid one XL after about a week and have generally been laying regular Large since.
The Cubalayas, Faverolle (1, I think) and Chantecler (1, I think) started small and still are. The Cubalayas won't ever lay anything bigger than a Medium, they are small birds.
(*) More reasonable if only because I have a TON of Large egg cartons, and no XL egg cartons
