I would not ever consider taking home any bird from that place, or any other place like that, as I guarantee you that all of the birds have some type of infections, if not serious Avian Viral diseases, as well as parasitic infestations such as feather-mites, and they are just passing them all around to each other. It's extremely sad and I know the desire to want to help and save just one bird from a place like that, but you are then putting your Green Cheek Conure at home at risk for anything and everything, even lethal/fatal Avian illnesses such as Borna Virus, Polyoma, and even PBFD. So you can't put your current bird at risk....I really can't believe that a place like that is allowed to exist in Florida (I'm assuming that's where it is since you live there). Most US States have much more stringent laws regarding the number of birds/animals that can be in one place, about cleanliness, etc. Even Flea Markets have to go through inspections by the state Health Department if they sell animals...It might be a good idea for you to contact the Florida State Health Department and find out what agency in your area/state is responsible for inspecting pet shops and then report this place, because this will force them to clean the place up and meet all of the standards that they have to, or they will face being closed-down or not being allowed to sell any live animals any longer...
****As far as the Moluccan Cockatoo goes, it doesn't sound to me like you have any idea at all what it's like owning one or being responsible for one. There are more Moluccan and Umbrella Cockatoos in Rescues and Shelters and up for Re-homing on Craigslist than all other parrot species combined, and there is a very good reason for this. People who are usually very well-meaning and who have a little bit of parrot experience with Conures or Amazons, or even maybe an African Grey or a Macaw decide that they want to bring home a larger parrot that is more cuddly, or more interactive, smarter, etc., so they either spend a small fortune and buy a young baby from a breeder for $3K or more, or they go onto Craigslist or to a Rescue and find one and adopt it...And they quickly realize why it has had many, many owners in it's short life, and why it's plucking...
The larger Cockatoos (Moluccans, Umbrellas, Sulphers, Citrons, etc.) are ALL extremely intelligent, like the intelligence of a 5 year-old human toddler, and what goes along with that is requiring the exact same care and attention as a 5 year-old human toddler requires, no joke. If they are not given that type of attention, interaction, and mental stimulation every single day of their lives, all day long, they become extremely neurotic, they quickly become horribly bored, and that's why probably 80% or more of them that you see in Rescues and that are up for re-homing are pluckers and/or self-mutilators, to the point that many of them (a good number of them) actually chew holes into their flesh.
It's extremely difficult to successfully own one of the larger Cockatoos if you work a job and aren't home 24/7...Think of how people deal with working and having young children. Until the kids are old enough to go to pre-school/kindergarten, they must put their young kids into daycare if one parent isn't a stay-at-home parent, or they don't have a relative that is home all the time and able to watch them while they work. And then eventually their children are old enough that they are at school all day long, and then at 3:00 p.m. they have to make arrangements for their kids to go somewhere and be watched by someone until they get home from work, unless they are lucky enough to be able to have one parent stay home all day long...Well that is pretty much the exact same situation you are putting yourself into if you bring home a Moluccan Cockatoo. You cannot work an 8-hour day and leave a Moluccan inside their cage for those 8 hours, because if you do, you're going to quickly have a very neurotic, self-mutilating parrot. They need constant care and attention, they must be constantly occupied and stimulated mentally with something, or they get bored and upset, and then the screaming starts (which if you have close neighbors you'll have an issue for sure)...and then the plucking starts.
And even if you don't work and you or your spouse or another family member is home all day long every day, they must be prepared to pretty much dedicate most of their lives to the Moluccan. I know someone who has had a male Moluccan for the last 11 years, and since he brought him home at the age of 3, 11 years ago, he has not taken even a long-weekend vacation. He is not married so he is solely responsible for the Moluccan, and he would be happy to tell you that 99% of his life is caring for and being with his bird, and the other 1% is when he's at work. He gets up every morning at 5:00 a.m. so that he can spend a couple of hours with him, making his breakfast for him each morning and then spending the other hour comforting him so he'll go into his cage so he can go to work...And then he has the luxury of working close to his house and being able to come home at noon for an hour, which he does every single day, so that he can let him out of his cage for an hour. Then he has to again comfort him so he'll go back into his cage, because the bird is smart enough that he knows that he's going back to work, and he fights it every single day...Then he comes home at 5 each night from work, and the entire rest of his day/evening is spend playing with the bird, cooking dinner for the bird, reading stories to the bird, talking to the bird, taking the bird outside in his buggy for a walk (he won't wear a harness), and putting the bird to bed. And that's his Monday-Friday for the last 11 years...And his entire Saturday and Sunday are spend with the bird, from the moment he wakes up at sunrise (when the bird wakes up) until the bird goes to bed. The only time he gets to himself to do anything, even just watch TV or read a book, is for an hour or two after the bird goes to bed and before he goes to bed. And in the last 11 years the only "outings" that he's had were 3 or 4 concerts he has gone to close to his home, and the only reason he was able to go to them was because his parents are able to come over to his house and babysit the Moluccan for a few hours while he goes to a concert. That's right, he has to get a babysitter for the Moluccan if he wants to go out for an evening. So he hardly ever goes out, even for dinner...He's in his 30's and has not dated anyone in the last 11 years, both because of having to have a babysitter for the bird, and more because whomever he starts dating is going to have to be the most understanding, bird-loving person in the world to be okay with just staying home every single night of their lives, and only in his house...And chances are that the Moluccan isn't going to be nice to anyone that he would date, because he'll probably be jealous as all-hell and could very likely be violent and try to hurt the person...So again, he just hasn't bothered...
Now you might think that this guy is out of his mind and that it's unnecessary for him to dedicate 99% of his life to the Moluccan...Well, all I can tell you about that is that his Moluccan Cockatoo is the ONLY Moluccan Cockatoo I've ever seen in-person that isn't a plucker at all, he's the most gorgeous, healthiest Moluccan Cockatoo I've ever seen by-far, not a feather out of place, shiny, healthy, and happy. So you be the judge of whether the way he lives is necessary to raise a healthy, happy Moluccan Cockatoo, because I guarantee you won't find too many, or any if you're looking in Rescues/shelters or on Craigslist for re-homing, that aren't plucked and/or mutilators, as well as horribly neurotic and aggressive...
