Unfortunately it's not really about the "eating," it's about the SCRATCHING. Like slow motion I've watched my helpless little seedlings crying out as they leave the dirt to fly through the air and die. Unless you can shackle and chain your chicken's legs (not a good idea,) you can't stop them from digging up your plants. They're not rabbits and they'd way rather eat all of the bugs and worms in the soil the poor unsuspecting plant is trying to grow in. Wire cages around plants and of course a wire fence around your garden is really the only way to go.
