If you do natural grains for your hens.... Just grind it up a bit (either bash it with a stone or pestle and mortar..) although I bought a little bag of chick crumbs, I've noticed that my broody who they are all 18 in with now, just makes her food smaller for them... And she must know! 2 pt wheat, 1 part barley, 1 part cracked corn..... So I'll just be doing that from now on
