While several species are relatively well known, the plumed guineafowl and the two members of the genus Agelastes remain relatively poorly known. These large birds measure from 40â71 cm (16â28 inches) in length, and weigh 700â1600 grams or 1.5-3.5 pounds.
Roosters typically weigh between 10 and 18 pounds. Chickens used specifically for laying eggs weigh less than chickens bred for meat. However, the weight of a chicken depends on other factors, as well. The type of diet, environmental factors and overall health all play a role in how much a mature chicken weighs.
