I'm in a Rural Residential area, and let the birds out all day to roam the property. Used to have no fencing at all and the roosters fought off coyotes and neighboring dogs a few times but it ended up being repeat attacks and kills from one neighbor's dog that made me fold and put up a 6' chain link. Of course HE didn't have a fence for either his dogs OR his pool (illegal, much?) and didn't offer any money for the fence that made his pool legal, even when I asked. But that's neighbors. You can't be too much of a jerk - they know where you live.
But yes, I used to close them in but now I leave them out unless I know I'll be home after dusk.
No problem with the neighbor's dogs digging under your chainlink? Our neighborhood strays actually broke down our chainlink gate which inspired us to ultimately put in block wall and iron fencing/gates. German Shepherds are STRONG.
