They like the goat weed and croton too. Croton is their favorite. Last year most of the birds we took were full of wheat and croton.
If you have them now, you'll likely have them when the season comes. If you have them coming through now you'll likely have them throughout the season. Any native seed producing grasses or plants or crops are preferred....

They feast on deer corn in December.
Standing crop okay. Must be two weeks after the cut date on the crop before the field is hunted, unless the rule has changed.

Whack 'em and stack 'em
