When I got our day old chicks this week, we gave them medicated chick starter. It's almost as fine as dust. Last night I bought organic chick starter feed, made by the same company as their other starter feed. When I opened the bag,I noticed the feed is a bit bigger than the fine feed they had before. They won't eat the organic chick starter!! So this morning I switched it back to the old kind and they ate it like ,crazy. What can I do? I want to feed them organic.
