Really hoping that you listing so many species of parrots you’ll be “picking up in a few weeks” doesn’t mean you “bought” a bunch of parrot eggs online!!!
As Chris said, parrot eggs are 100% certain to be a scam. I’m not sure what is possible for other birds, but the eggs of parrots cannot survive for long outside a very expensive brooder for exotic eggs to keep them at precise temperature, humidity and I believe it needs to rotate them too OR to ideally leave them under the care of the parent birds. If you want a black palm, you’ll be looking in the $25000 range, minimum, IF you can find one at all. No actual breeder of these exceedingly rare birds would sell someone an unweaned baby, except perhaps to another breeder with an extremely good track record and years of experience hand-feeding baby cockatoos.
May I ask what your intention is with so many widely different species of parrots is? Usually breeders of large and extra large parrots specialize in a single species group, like exclusively breeding macaws or exclusively breeding amazons, though they may have several pairs of different species of macaw or amazons etc...still making for a large and profitable operation. Having so much....variation in species may make what I can only assume you’d like to develop into a business kinda sound more like a bird mill than an experienced breeder who gives ample time and attention to each baby. Most people are willing to pay far more to a small scale breeder who produces exceptional babies than a large operation that churns them out like an assembly line. Unlike reptiles (I looked at your profile and see you breed them), parrots need to be cared for on an emotional level as well as be socialized from a young age. That’s very hard to do when you have numerous babies at once and of different species (as they all differ quite a bit).
