For free-ranging deer visiting a backyard, the better default is not to put out food, salt licks or mineral supplements. A list of foods deer will eat is not a safe feeding plan. Concentrating wild animals around a feeder can create disease and neighborhood problems, and feeding may be prohibited where you live.
Check the wildlife authority before taking action
Rules vary by jurisdiction and can include food, bait and mineral attractants. New York DEC prohibits intentional feeding of wild deer and moose, with specific exceptions. That is a New York rule, not a claim about every state. Ask your own wildlife agency for the current position at your address.
The fact that a shop sells deer feed does not establish permission to use it for visiting wildlife. Advice for licensed captive-animal care or an agency-managed program is also not a general backyard prescription.
Why a feeder can cause harm
A reliable food pile attracts repeated visits and concentrates animals. DEC’s chronic wasting disease guidance explains why artificial concentrations can increase transmission between deer. Cleaning a feeder does not remove every consequence of bringing animals together.
Consider the broader location too: food near homes and roads can encourage deer to cross traffic, damage neighboring planting or approach people. A small portion, a changing schedule or a product marketed as balanced does not establish that feeding is harmless.
What about apples, corn and salt blocks?
Do not use a menu of fruit, grain, hay or commercial pellets as reassurance that a backyard ration is suitable. Wild diets and digestive conditions vary with season and place. Mineral licks are attractants too; they are not an automatic health improvement for wild deer.
Winter feeding has additional digestive and habitat concerns, covered in the separate winter deer guidance. Avoid starting an improvised feeding program in response to one animal looking thin.
Support habitat without creating a feeding station
Ask local wildlife or conservation staff about appropriate habitat work on your property. Preserve suitable existing vegetation where practical and choose regionally appropriate plants, while considering roads, neighbors and garden protection. Habitat planning is different from repeatedly placing food in one spot.
Secure animal feed, waste and other unintended attractants. Watch deer from a distance without approaching, touching or hand-feeding them. Keep pets under control. If the animals change behavior because you are close, give them more space.
If you are concerned about an animal
For an injured, trapped or unusually behaving deer, contact the wildlife agency or an authorized wildlife professional. Describe the location and behavior and provide photographs taken from a distance if requested. Do not capture, transport or medicate it yourself.
If you have already been feeding deer, explain the duration and food involved to the agency and request advice for ending the practice. Do not replace one feed with another or invent a tapering schedule. The next step should be based on the local situation rather than a generic daily ration.
