Just curious how many mix their own feed. We are having a problem finding the feed we want around us. My husband wants to just use cracked corn and soymeal. I am researching this and find that corn raises body temp. I live in Iowa and our summers are hot. My chickens have to be in a coop all day sometimes when we work. I do have 2 good sized windows and run a fan for them but still am concerned about the corn issue. I have Storey's Raising Chickens and see the recipes in there. They also list corn as a possible ingredient, main ingredient but I wonder if I need to subsitute a different grain in the summer. If you are making your own feed I would love your recipe.
