Deer have evolved to survive the stark winter months, with adaptations like a warm winter coat and stores of body fat they can use for extra energy. The animals also reduce their activity and food intake to conserve energy and migrate to a forested shelter called a deer yard, which can provide some protection from the elements.
“Although people may feel badly for deer and want to help, the Fish and Game Department would like to remind the public to never feed deer as it may actually harm them,” said Becky Fuda, the deer project leader at New Hampshire Fish and Game.

In 2015, 12 deer were found dead around a feeding site in South Hampton, after they were given food they could not digest, according to Fish and Game.
Microorganisms in the deer’s stomach help them to digest food. The natural diet of deer gradually changes with the seasons, and the microorganisms also change over the course of a few weeks to help them digest different foods.
But a sudden shift from a high-fiber woody diet to a high-carbohydrate diet offered by humans can disrupt the deer’s stomach chemistry, making deer less able to digest food, and releasing toxins.
And Fuda said feeding can have other negative consequences for deer, like increased risk of getting hit by a car and increased risk of disease transmission.
“Fish and Game strongly discourages the practice,” she said.
There are about 100,000 white-tailed deer in New Hampshire, according to an estimate from Fish and Game.
