At birth the fawn weighs 6 to 9 kg depending on the origin and the living conditions. On average, the males weigh 500g more than the females.

During the first months of life, growth is rapid. Fawns take 300 to 400g per day and reach 45 to 60 kg at 6 months. The growth lasts up to 3-4 years in the doe, reaching 160 to 230 kg.
The food richness of the medium determines the speed of growth.
A female is called faon until the age of one year, bichette between one and two years, then biche beyond. Adult deer are sometimes referred to as large deer. A hind is said to be followed if its fawn accompanies it, leader when it is at the head of a herd that it seems to lead.
