Every breeder is different, as Karen said. And I've never
met a breeder who makes much in the way of a profit, they spend too much building aviaries, buying parent stock, feeding babies, feeding parents, etc. Most are lucky to break even after a few years, especially breeders of the particularly rare birds. Keep in mind, a proven breeding pair of Hyacinths runs around $30-50k.
I've met small backyard breeders, who only breed a few pairs of p'lets or tiels, who claim to hand raise and raise sickly, untame, sad little babes. I've met mass, nearly commercial level breeders, who have the best facilities EVER and raise the sweetest, most tame birds! It's such an individual, localized thing.
Those ladies look like we would have at the pet shop... Only difference is there would have been 3 of us, not 2. With two part time helpers to clean and stock. There were only 3 of us working full time to feed and socialize the babies, and we had probably as many birds as that photo in the spring time tho with more variety in species. Our birds were ridiculously well socialized, well fed, and well adjusted. It's really a matter of each breeder's dedication and priorities
Personally, it does make me a little sad to see so many birds in that photo simply because I know there just aren't that many perfect homes for them. BUT at the same time, I know I'm a pessimist and for all we know those ladies screen potential buyers and make sure the babies end up in a good home. If I were to judge a breeder simply based on them making sure all the babies were well socialized and had good homes, the bird breeders would be at the bottom of my list... dog/cat breeders would be who I would go after
Thankfully, birds are just unique enough there aren't millions of them neglected and abused.
It's a very sensitive, personal topic and I know everyone feels differently. I know, especially on the other side of the pond, it's even more sensitive because people in the UK are much more pro-animal rights. Which is great, I really wish people could be more active and passionate about it in the States! Sometimes it goes a tad far
Had to defend myself to Gareth's aunties from the UK who thought I was a terrible person for keeping birds as pets and trimming wings, for having a cat that doesn't go outside, and for wanting to work at a zoo. They practically accused me of neglecting/abusing all my animals! Until I dragged them over to my house and showed them how I keep them (and how much Goober hates life and everyone in it except me and Gareth lol)
