I have 1.5 acres and I let my chickens roam any where they want. Some parts of my property are fully fenced and others aren't. And the area my chickens aren't fully fenced in, they have discovered my neighbor's way over saturated/expired leach field. There is standing water (crap water) in spots. If there wasn't water, I wouldn't be concerned. Anyone deal with this before? I'm worried that they will get sick (or we will get sick). And I can control the situation better by putting up more wire fencing. So, I'm going to do that soon. The main concern is their health and ours? Am I too worried?
