Tried chicken wire, they fly over it. tried moving the coop farther from the neighbors' barn, and it didn't help at all. and I want free-rangers but they will not stay in our yard. in the morning they all sneak over there while we are all at school/work and won't come back until later in the day, and a couple hens even started nesting over there. The neighbors keep goats and sheep in said barn and they don't appreciate our poultry wandering over there. I wanted to expand my flock in the spring and I feel I need to tackle this problem before getting more chicks to potentially follow the first flock's lead and hang out at the neighbors' all day. Help?
