I live in the mid-Atlantic region kind of 50 miles Northwest of Washington, DC. Not really new to the area, but I still feel like I don't know how much useful vegetation/"stuff" the birds will be able to find in a typical yard/pasture/woods area over the winter. Any ideas? These birds run the gamut from guineas to turkeys and it's my first winter with them. Regardless, I'm overwintering everyone, but I'd still like to know if it will be really sparse pickins for them, or if they'll find some significant food sources by free-ranging in the meanest of the weather to come. My guess is very little, in which case I'll be buying LOTS of food.
