I have a 20x30ft garden and the slugs and other bugs in there need to go. I'm growing 400-1000 lb pumpkins, and I really want to save them from being devoured by the slugs. It is completely organic, so no pesticides. My flock is new, so they've been penned so far, but will be slowly let out to free range. I would love to use my girls (and guy, because he's a slug machine) to clean up the bug issue. IF I let them in, it would only be when I'm in there weeding/harvesting.. But will letting them in entice them to fly over the fence later on when they have total freedom? I certainly don't want my garden trashed; contents include pumpkins, cantaloupe, watermelon, cucs, carrots, sweet potatos, squash, corns, onions, beans, and will be starting broccoli & kale for fall harvest. Anything in particular they will try to go after (whether I end up letting them in or not)?
