@21308Well, it's not like quiet(er) parrots don't exist, and lots of other birds are quiet! Small parakeets (linnies, budgies, and bourke's come to mind) are very quiet, as are parrotlets. I've heard cockatiels, especially females, can be quiet but I'm not sure if that's true since the only ones I handled were in a group of three (named mohawk 1, mohawk 2, and mohawk 3, I kid you not) and obviously much noiser and messier. But I'd rather their whistles and shrieks over the shrieks and screaming of most birds. Lovebirds can be pretty loud despite what I've heard people say, and Greater Vasas, pois (Eg; senegals, meyers, red bellies, brown heads), pionuses, and some smaller conures are quiet through most of the day generally, but can be pretty loud at others. I heard pionuses are particularly quiet of this group. And most African grays adapt to the noise level of the house, but most I've known weren't very quiet.
But yeah, having a cockatoo or mawcaw when it comes to noise is a huge no-go. And I'd highly discourage people from owning them unless they're very experienced, and have the time, space, money, and tolerance for these birds.
As someone who's had both goat and sheep milk (and hates cow milk), sheep is definitely better. Sucks it's not available here in Canada. And goat wool is definitely more comfortable. Maybe it's different here because in Kurdistan all goats I knew were super friendly...Probably because they've lived alongside us for a very long time both as food and companions, and even in present day there's still many nomadic goat herders. Most sheep I've met are really cowardly though.
