They may be first for the lifeboats, but they are also first for the bullet. In fact it's the youngest of all that goes to the front of the queue.
Young red deer are called calves.( A fawn is a young roe deer.) In red deer the young may stay with the hind for as long as two years. There are some regularly seen on Blacka and around where the mother and young are inseparable. Some pictures on this site can be found showing hind and calf of various ages.
When they decide to kill hinds it's claimed that shooting its calf first is humane or merciful. I won't trouble this space with the rest of the reasoning.
