Cracked Corn is an inexpensive way to keep squirrels and medium-to-large birds happy.
Doves, as well as Jays and Crows will take corn opportunisticaly, as will the various "black bird" species. Corn is also highly desirable to ducks, geese, pheasants, turkeys, or other similar "game birds".
Cracked Corn does not sprout and will not leave hulls.
To serve anyone, simply scatter on the ground, or if you need to limit to crow-size & smaller birds (or to squirrels), offer corn as part of a mix in a platform/tray, or on a railing or other surface no larger than is necessary to service your desired species.
