Wow, you took me seriously
Pros:
Beautiful
Mine have gotten along well with all the other birds (check my sig). Although the one cock has started chasing my Tom, we need to get a bigger pen built (just moved). Loud is a matter of opinion, they make a call, some people say it sounds like 'meow', 'hey you', during mating season or when disturbed, they also 'honk' when disturbed. We haven't had the neighbors complain yet
, and I think the roosters can be worse about all around noise, and then the guineas
, maybe we just have understanding neighbors.
Cons:
Need a bigger pen than chickens, if not free ranging (at least 10-ft wide and 6-ft high to accomodate the males train)
They can fly.
If free ranging they have been known to wander off. To curb that you can keep the female penned and just let the male out, or just make sure your property has the best food around.
Have heard about them attacking metallic blue cars (looks like another peacock) and roosting on cars, roofs etc. with resultant mess.
We love ours, and make a little money to help with their upkeep selling feathers and chicks (when we have them).
