Interesting that in the third paragraph of 'a' it states "It is therefore important to have pullets, prior to lay, on a high level of calcium to store it on body." Does this mean that there should be calcium available to the pullets before the 'expected' laying dates? If so, how long before as the article also talks about potential damage further on?

I know.
I really like that whole article.
I've been working on a project about eggs/eggshells and I just came across that page in my research.
I find it extremely interesting!

And it's hard to know when exactly they will start to lay. I know mine did not all start when I expected. Perhaps calcium on the side available from the time they start squatting?
