Anyplace that sells chicken feed should sell cracked corn. It's cheaper than other feeds, but much lower protein, so don't make it the main course. Think of it as a "Snickers bar" for birds, great energy potential with all that sugar and fat, but not a main part of a balanced diet. In the winter, they will eat more calories to keep warm, that is where cracked corn is really useful.Alright yeah thats what I was a worried about if I was to do it was a fire starting because of the heat being over the bedding but thank you guys I was just worried about them freezing. And the cracked corn can I just get it from any farm supply store?
