Hopefully they were just interested in the design of your coop. My friend and I sometimes see something we like at a house and stop to look, only to see how they did it. We have stopped and looked at garden plots, chicken coops, baby lambs in the field, stuff like that and I'm sure the folks that own the property wondered what we were up to. We weren't invasive, just getting ideas for our own gardens and yards. Maybe it was just something innocent like that.
