That is terrible. I hope you will talk to the seller about proper management and care of both birds and other animals. I don't know how involved you want to be in this. If you're willing to invest some time, you should stop by her property yourself to talk to her, and maybe get a look around. If you don't want to get too involved, it would be nice if you could still call animal welfare or even the local game warden to do a check on her property. She could be selling to other people, and I feel terrible for all her animals anyway.
