I asked a biologist friend of mine what's best to feed the deer to help them thru winter weather. He told me that while lots of folks feed shelled corn, it's not always the best of ideas as their digestive system can't always handle it and it can be fatal. That led to a call to the local farm co-op, who told me that yes, deer have trouble with shelled corn due to the shell of the kernal being so hard. He suggests a mixture of cracked corn and steer fattener, both of which have nutritional value. Hope you find this information of interest and value.
