I went to the natural food store and the feed and garden center we get our dog and cat food from, and got everything they need... the RIGHT things this time. I got plain 100mg niacin and brewers yeast as well. I also changed their food to a flock grower to make sure it is unmedicated. So, I'll be waiting on pins and needles for a few days, but that will give me a chance to redo the blueprints for the coop. Going to make it a duplex. Thank you to everyone again for all of the advice, information, patience, and kindness! I will continue to update on Bernese as she progresses.
