Okay, I'm not a good gardener. Growing up my family had a HUGE garden or two. I would pick all morning, wash, cut, cook, and can all afternoon in the summer time. So I've tried to grow over the years various things like tomatoes, cucumber, squash, peppers, lettus. Simple stuff, but I've never really accomplished any thing major. So this year we are going to do square foot gardening. I know I have to put up a fence or my chickens will demolish it. So how high do I need the fence to keep them out or other deterrents? Pictures would be nice, but that may be asking a bit much. Need ideas that look nice but aren't going to cost me more than my new coop. TIA, Melissa
