hello! I have 4 hens that I want to start free ranging on my property but I'm a bit apprehensive because my neighbors flock of about 18 hens and roosters sometimes wanders onto my property so I'm not sure if they will end up overlapping where they are foraging. their flock seems to be in good health but I dont want my hens to accidentally be exposed to their roosters. any suggestions on how I can keep them sepparate? im considering putting up an electric fence for my goats which may keep them apart.
