Hi, I am going to get 7 Red Star chicks tomorrow, my first batch of chicks!! I have a medium-sized backyard completely fenced in. The fence is a little less than 4 ft tall. We want the chickens to roam through the backyard (and eat all our ticks!). But I don't want them getting into our neighbors' yards. We have the road on one side and three neighbors on the other three sides. So my question is: should I let them roam the backyard? Or will they jump the fence? And I've heard that they come back to the coop at night. I know my neighbors won't want chickens in their yard. If they get over, will they be able to jump back before night? Or do I need to go after them?
