The same site will have very little natural food to offer the following year. Concentrating deer around feeders near our homes, may cause a number of problems. Property damage in the area may increase by their browsing on ornamental shrubs and trees. They may become a hazard to local traffic as they move to and from the feeding site. Domestic dogs will begin chasing and even killing deer.
Deer are more vulnerable to coyotes during deep snow periods.
If deer concentrate at a supplementary feeding site that is not associated with adequate cover and opportunities to escape predators, they may be more easily taken by coyotes. Deer that are concentrated, regardless of snow depth, are more susceptible to disease. Improper diets are often fed. These lead to digestive upset and potentially death. If not enough food is provided or if it is not distributed properly, aggression and fighting will occur at the feeding site.
