Nearest next alternative is 450 miles away. I have enough to get through a few days, and it's on order at the feed store, but if I run out, what can I substitute? I have oatmeal in the house and oat bran to start with, but what would I need to add to that? The chicks are only 9-10 weeks old, so I don't want to buy the layer ration yet. I also have access to pelleted horse feed, and wild bird seed, and I can get some of whatever Fred Meyers has in their bulk food department. Any suggestions for a simple short term home recipe?
