I don't know how to post a link to another thread, but "Vitamin D supplement?" from April has one really wonderful post about vitamins and minerals. So far what I'm reading, hens can synthesize vit D from ultraviolet light "through" their feathers. Don't know what exactly "through" implies though. Several other threads I came up with when searching the subject also wondered about the connection between low light levels and shell-less eggs. So, it seems to be one factor.
the fact that I thought about consulting books before the internet, or even BYC, shows my age.
