I have yet to find anything the deer like more than corn... If corn isn't bringing them in, I am not sure anything will. Soybeans and black eyed peas would be use similarly. I have never used black eyed peas, but with soybeans, you generally have to start the mix out with a low percentage of beans and then work your way up until they make up 75% or so of the mixture. You need at least some corn in the mix for them to eat it. Perhaps peas are a bit difference?
