Another option to consider would be a solid style fence . In an article in Deer and deer hunting' s Sept. issue the author describes an experiment where a fence made of ordinary burlap 66" high successfully repeled nearly 100%% of the deer who approached it . Even attempts to train the deer to jump the fence by gradually raising it from 24" to 66" were not entirely successful in getting them to cross the fence . This despite the fact that food was clearly visible at all times . The food in the control areas was routinely consumed as soon as the feeders activated . Another article that I saw years ago stated that deer are reluctant to cross a fence if there is another fence clearly visible on the other side . The example given was a 3' outer fence with a 5' inner fence 3 ' apart . This is definitely food for thought .
