Ok, 2 questions. I hadn't given any thought to this until today when my chicks began jumping out of their brooder, but now I'm worried about my fence. My focus was on keeping the predators out, but I hadn't really thought it would be a problem to keep the chickens in!! My fence is 4 feet tall. I started reading about it today and apparently they can clear 4 feet easily and even 6 feet won't keep them in if they want out. So what do I do? My main concern is them jumping the fence and getting eaten by dogs. Also, I'm about to plant some more grass seed and other plants in their 'yard' (everything should be established by the time I get them out there) and I was wondering if I planted a garden or put some raised beds/planters in there, would they just destroy the plants or would they pick what they wanted and let the plants grow?
