What is defined as 2 or more kits being raised together?

The correct answer is "a litter," which specifically refers to a group of two or more kits (baby rabbits) that are born and raised together by the same mother. This term is commonly used in the context of rabbits and other mammals to describe the offspring produced in a single birthing event.

Using the term "litter" establishes clarity and consistency in animal husbandry, as it conveys not only the quantity of the offspring but also their relationship as siblings from the same breed or parental lineage. This terminology is important for record-keeping and understanding genetic traits within a group of rabbits.

The other terms, while they may describe different groupings or collections, do not have the same specific meaning. "A nest," for example, refers to the place where the kits are born and cared for, rather than the kits themselves. "A batch" is more general and could refer to any quantity of items that are considered together, while "a group" lacks the specificity needed in the context of rabbit breeding and care.
