A conservationist’s tips for feeding (and photographing) your backyard deer. Enjoy the thrill of your own backyard with this handy guide to feeding whitetails.
(Note: Techniques described in this article are merely suggestion, please consult your provincial guidelines for supplemental deer feeding)
As a dedicated whitetail conservationist and wildlife biologist, I have managed winter whitetails for more than 25 years. From deer yard operations in the mountains of Quebec, to counting pellet groups in Central Ontario as part of a Ministry of Natural Resources (MNR) Fish & Wildlife initiative, to today running my own small scale backyard feeder in Eastern Ontario, working with Ontario’s deer populations has been an incredible part of my career.
Helping our ‘deer friends’ endure the colder months is a pet project of mine and it can be yours too. If you’ve noticed deer in your backyard or neighbourhood over the years, now is a great time to learn more about backyard feeding. Here’s a handy guide to help get you started! The rewards of backyard deer feeding are well worth it. In the spring, I see fawns born that develop into mature majestic bucks, who later return to my feeder each winter. Knowing I play a small part in the ‘whitetail circle of life’ is a good feeling indeed!
Meet the White-tailed Deer
White-tailed deer or Odocoileus Virginianus are a wide-ranging ungulate native to North America and South America and found in most parts of Ontario. Whitetail body size varies greatly throughout its range, following Bergmann’s rule, where deer of the south are generally smaller, while those in northern climates like Northeastern Ontario tend to be larger. An adult whitetail can weigh between 150 – 250 pounds, on the hoof.
Tips on backyard feeding
Backyard deer feeding is an enjoyable pastime and of benefit to whitetails as snow depth increases. I learned a few tricks to assist with your own backyard feeding, starting with the number 1 rule of winter deer feeding, consistency. Once you begin distributing supplemental feed, it is imperative to continue throughout the winter, as a whitetail’s digestive system adapts to your supplemented diet. Understanding the basics before you start feeding, will go a long way to ensuring a more productive and helpful winter program. It is easy to do with a few simple tips.
Backyard feeding VS Deeryard Management
While government agencies operate larger scale deer stations in northern Ontario deeryards to help manage winter whitetail populations, it is much easier to run your own small-scale backyard feeder – as long as you follow these handy tips. Please note that supplemental feeding is not the same as a full-fledged deeryard operation, or an emergency feeding situation. Your backyard feeder will serve only as a small ‘supplement’ to the deer’s natural winter browse intake, akin to feeding song birds at a bird feeder. We are not there to replace a whitetail’s natural diet entirely; this is one of the many misconceptions of backyard feeding.
This guide covers supplemental feeding of a small number of deer, usually less than 10. I generally provide feed for 6-8 whitetails each winter.
The main motivation for backyard feeding is to prevent loss of wintering deer due to starvation. Whitetails in the northeast contend with deep snow, limited access to natural forage and increased predation. Supplemental feeding is an asset to the herd as a whole. Younger deer have higher energy demands and with increased difficulty wading through deep snow, winters are especially hazardous.
Mature bucks enter the colder months having depleted fat reserves during the rut and when winters arrives, they are often in a weakened state; unable to replenish important fat levels. Studies have shown that doe’s with improved winter nutrition have fewer fawns die at birth, and increased fecundity rates, or the delivery of multiple fawns. Improved winter diet is beneficial to all members of a whitetail population, and is the cornerstone of any backyard feeding.
After years of experimenting with different feed types, I settled on ‘livestock grower pellets’ from Ritchie Feed & Seed, in Ottawa. These grower pellets are composed of 14” Protein, 8 % Fiber, 3 % crude fat and 1% calcium and available at many other livestock feed stores in Ontario’s northeast: Krause Farm Feeds in Powassan, and Valley Farm & Feed in Chelmsford. Take note that the use of whole corn, whole wheat or whole barley cause digestive issues for deer, since these foods are high in starch.
For the small number of deer that visit my backyard feeder, 1-2 litre ‘scoops’ of feed per day will suffice. Deer usually only feed for 2-3 minutes and then move on to their natural winter browse. I make sure to have feed in my feeder at all times that is dry and accessible. If I plan to be away for more than a day, I arrange for someone to top-up the feed so it never runs out.
One pitfall of winter-feeding is its impact on deer density. Large-scale feeding operations can increase whitetail numbers, thus depleting natural forage supplies. This ties-in with the concept of carrying capacity or the environment’s ability to offer life support for a set number of animals, based on available resources. The goal with any backyard feeding is to offer just a small supplement and not to replace natural feed completely. Keep your backyard feeding small scale; cater only to a small handful of deer.
Helping the offspring
One devastating hidden effect of a harsh winter is observed with adult does, and often results in death of fawns during birth. Studies have shown that females with improved winter nutrition have fewer fawns die at birth, and increased fecundity rates, or the delivery of multiple fawns. Improved winter diet is beneficial to all members of a whitetail population, and one reason why we offer supplemental winter feed.
Conservation at work
As active conservationist of Ontario’s northeast, assisting deer populations during difficult months is both fun and beneficial. Maintaining a small backyard feeder has offered me an intimate glimpse into whitetail behaviour, rarely seen, and made for great photo opportunities. Good luck with your own backyard whitetail feeding. Our deer friends thank you.

The deer are coming to eat sun flower seeds. Is this good or bad for them. The come up on the deck where the feeders are and eat the peanut butter and sunflower seeds the fall or are with in reach.
Cynthia, this is all normal browsing behavior from whitetails, not to worry. Winter diet is pretty limited so late fall they try to bulk up a little…enjoy the sights of our deer friends!
Sorry Cynthia, prob not the best winter diet for deer…
I have approximately 10 whitetail deer that come everyday. They have been coming for 3 years now. I have always fed them whole corn. Is this wrong?
Hi Kim, sorry for the delay..your message went into my spam folder. I have heard that whole corn can be more difficult to digest…but i also have a colleague who uses it without reprisal… good luck!
