Mink will breed during the spring (February to April) with males travelling vast distances in search of a mate, they will try to mate with any female mink they find and then move on in search of another. A female mink will look for a den site once she has mated to raise her young; den sites are usually cavities in tree roots at the water’s edge, rabbit burrows or in a pile of rocks. However they will make a den practically anywhere, e.g. under/in sheds, windmills, reed/sedge stacks, under cattle grids and we have seen them in a thatched roof on a boat house. The young (known as kits) are born in late April to June after a gestation time of 40-75days, with a typical litter size being 3-4 kits, some litters can be larger but this is rare. Kits are entirely dependent on the mother’s milk for 3-4 weeks, and are weaned after 6-7 weeks. From August to October juvenile mink will become independent, their mother will discourage them from the den and they will leave to find their own territories. Mink are very capable hunters during the winter and do not hibernate and both male and female mink will take winter-surviving water voles before they have had a chance to breed.
