I would just like to point out the following:
1. We don't know (and they don't need to tell us) this family's financial situation. Money is only trivial if you have enough of it, and not everyone qualifies for loans, credit cards, or Care Credit. Even if you qualify, Care Credit definitely doesn't pay for gas to get you to a specialist in a different town, or for the missed wages if you have to take time off work. This bird very likely needs surgery, and that is not cheap.
2. The shop/breeder will keep doing this to other baby birds if not held accountable. They might still do it even if they are held accountable, but it's worth kicking up a fuss for the sake of all those other babies and their adoptive humans who will have to go through the same pain and stress. If they don't care about injuring baby birds and then selling them, they may care about Better Business Bureau complaints, negative Yelp reviews, and having to pay for treatment. Hit them in their wallet.
