(Sorry, I don't know much about pricing, I've only ever rescued peachicks)
Peahens will not lay eggs daily, and will only produce a clutch of eggs naturally in Spring, once fertilized by a cock. The hens will lay around 3-6 eggs in a clutch, but if you are looking to breed more in the upcoming years, you can take the eggs for incubating, and the hen will continue to lay her own clutch. She can lay up to 30 eggs in one season, with this practice(Although, I would not try for too many, as it could cause stress on the hen)!
Also, to my knowledge when living with my Indian Blues, both males and females will crow, but the females wont as much. Both sexes will also make honking noises, along with various other sounds. Peafowl will often honk and cluck when they feel threatened, and create a chirping sound for the first few years of their life.
(Once, when a hawk had flown over one of my hens with chicks, she even created a loud growling sound!)
As for coops, I recommend keeping chicks in a coop until they are at least 6 months old. This is because, they are vulnerable to predators(snakes, hawks, coyotes, etc), and also because they won't stay in the area unless familiar with it!
I've only ever raised Indian Blue peafowl, but all of my fowl have been very docile, and even affectionate! I raise my birds by hand, and try my best to have a close relationship with them, and because of that, they enjoy greeting me, grooming me(to the best of their abilities), and cuddling!!
