Woman tries to trade kids for a pet bird

I know some people get pretty obsessed with birdkeeping, but would you swap your kids for a pet cockatoo? Turns out one woman in America did just that. According to this story on CNN News Donna Greenwell, from Louisana, traded two of her foster children, aged 4 and 5, for a pet cockatoo that was on sale for $1,500. I wonder how many children you'd have to trade for a rare macaw? Or a budgerigar?
