I purchased the Countryside Organic chick starter and there are some pieces of grain and other bits with texture, but the majority of the feed is dusty and ground as finely as cinnamon and similar spices. My chicks (almost 4 weeks old) don't want to eat the finer stuff, so I find myself dumping out the fine stuff they leave and replacing it with another scoop of feed which pretty quickly gets eaten down to the fine stuff, then they leave it. I guess I figured crumble had some texture to it, and this is super fine. Is that normal? Should I try to leave it longer for chicks to eat, am I wasting perfectly good feed when I throw out the powdery stuff? It's finer than the sand I have in their pen if that helps the picture. Thanks!
