Hop over to the predators section and ask to borrow some pics of what happens to chickens who aren't protected... accidentally leave the door unlocked, bears, neighborhood thieves, snakes, dogs digging under or ripping through pens... and that's for the owners who actually TRY to protect their flock and with full grown birds... these little ones have no chance at all. Maybe if you show her pics of what her little kids are likely to find one day, guts and all, she'll get it through her thick skull that it's not going to be fun for all.
Then maybe Cochin's idea of asking Floridians for help might work...
