Thanks for the advice. I threw the grass out right after and they are doing fine. I have them on straw feeding them grower feed and moving them out onto grass every day for a couple hours.
For other interested viewers information; I did loose two bourbons within the first 3 weeks. A third bourbon fell sick for a day around four weeks but pulled out. All others seem to be fine. Initially I had four each bourbons, blue slates, chocolates, and royal palms.
