Its my experience that people just decide they want birds, so they get them. Most of them think you can just throw out bread or corn for food. I have tried to talk to them more before they come buy them and even have a print out with food and housing info, etc. I've had several people that I've turned away even though they drove for hours to get to my house. One guy showed up with a lidless box and wanted to tie the chicken's legs together for the ride home so they wouldn't fly out. Its truly ridiculous sometimes. Its not your fault they dont listen. If they are that ignorant on the subject you dont want them buying any more of your animals anyway.
