My local feed supply place just retired and closed its doors. I have been feeding Purina Game Bird Layer, which the special ordered for me. Because I didn't know they were closing until I walked in and it was their last day, I had to buy a Flock Raiser that looked very similar from TSC. I woke up yesterday to two birds dead, from what looks like starvation, and many other with picked at heads. They are not over-crowded, their feed was NOT empty, there is no change except the food. Today, I found a new feed mill (much farther away) that can order what they were eating before, the Purina Game LAyer. They also have access to ordering other products, including organics....I don't want to stress them out in the coldest part of winter, but I would like to try switching to an organic feed by summer. Does anyone have experience with organic feeding? What has your experience been? Do you supplement in addition to it? Any expertise would be much appreciated!
