That is good information thanks! Also it is a great endorsement for the breed.They are just a year old.
Did you track when they began laying? Most Cream Legbars in my experience lay at around 24-weeks.
Their first pullet year they go gang busters.... Some take time off during the molt -which usually happens around 18-months old...then they begin again. I have one that just turned 3 - and before she started her molt - she was amazing me by still producing a daily egg. She has just now started up again. I wonder how long she can continue to be a good layer. Then I have another one - that was once-upon-a-time a stellar layer -- but she started molting last July and still hasn't begun her laying again. She is a slacker IMO.
Over winter, I generally expect them to rest a bit--- I don't use artificial light for their coops.
