What is the given name to a deer collection?

There isn't a commonly accepted collective noun for a group of deer.

However, some creative suggestions include:

* Herd - This is the most common term, but it's usually used for larger groups of animals, like cattle or buffalo.

* Run - This term is sometimes used for a group of deer, especially in a specific location.

* Pack - This term is typically used for groups of wolves or dogs, but it could be used poetically for a group of deer.

Ultimately, the best term depends on the context and what you want to emphasize.
