Quote: curious what do we need to feed them and what kind of soil is best. I'm thinking I won't be changing the soil but the feed maybe.
This is one of several reasons why alfalfa meal is part of my ration.
I don't believe dirt is an issue if your ration is balanced properly.
That said... many production reds have white legs.... think about it... with leghorn bred in. I have some production reds crossed with buff orpingtons... heavy layers, pure white legs. And they are being fed the same ration as the HRIR. So, genetics first, but yet if the genetics is there, a balanced ration will bring out the qualities you want.
