Litter (animal)

A birth colony is the offspring at one birth of animals from the same mother and usually from one set of parents. The word is most often used for the offspring of mammals, but can be used for any mammal that gives birth to multiple young. Biology In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. A litter is defined as anywhere between three and eight offspring.
