I've never seen any, much less weighed any, lol, I just looked on the web and the page I saw said:Green peafowl are taller than IB peafowl not necessarily bigger.
"The adult male weighs 3.85–5 kg (8.5–11 lb), which is around 4 times as heavy as the adult female, at 1–1.2 kg (2.2–2.6 lb)."

Don't know how accurate the above info is, but I do know for a fact that my IB hens weigh 3-4kg and the males weigh 4-6kg, and you all know how funny I am about weighing, lol.
