Brood

 

the young members of a family of birds or mammals (hatchlings, litters). Sometimes the term also refers to the offspring and both parents or one (in polygamous species). The number of young animals in the brood or litter varies greatly from species to species, depending upon their fertility; for example, birds can have from one to 24 hatchlings, and mammals can have from one to 20 young. Even within one species the number of young can vary; in particular, it depends upon the climatic conditions of the year and other such factors.
