Thank you for the link, it is very useful.Here is a sample of egg colors from the UK, and my legbar pullet's first egg was similar to C15 on the chart...

It's bluer than green and greener than blue. :O) Here it is
on a light blue towel for reference....and that is a plastic tablespoon in front. (pullet egg aka little) -- It is a difficult color to capture.
I would also say--- if you get the opportunity to get cream legbars...then take the jump...they are no more difficult than other chickens to raise. (I felt I wasn't ready yet either...but I'm particularly glad that I got them.) HTH
