I feed my oeg bantams layer feed and cracked corn. I also give them treats of wild bird seed, lettuce, oatmeal, and whatever else I have that I think they would like. This winter, they tend to dig through the feed and mostly eat just the corn. Does corn have enough nutrients in it? Should I take the corn away so they have to eat the layer crumbles? Corn is supposed to be good for generating heat, so I really don't want to quit giving it to them. (I live in Minnesota and they need all the heat they can get
).
Any suggestions or am I worrying over nothing?
