ARe chickens hard to round up? right now we have 4 and they usually are in their crate when its time to lock them up. We need to build a coop soon as they are getting a little big for the crate. But I want to build the coop knowing that we might get more (planning ahead). So are they hard to round up? I'd like to do what we're doing now - lock them up at night, let free roam during the day.
