I keep everything from various peacocks, quail, pheasants, bantams, ducks, egg layers etc. Anyway the point is : I feed them all a mixture of wild bird seed, cracked corn, wheat, oats but mostly 26% game bird starter crumble. Over the past year or so, I notice that they are not finishing their crumble. The birds will be hungry and I have to dump what is left and put in new crumble. There seems to be low quality fillers in the food that the birds just won't finish up. I reckon that 10% of the crumble ration is wasted. I wonder if anyone else is having this problem.
