Indeed.
I have a “secure” coop ... but I still trap chicken eating critters that surf the yard ...
But I’ve been pretty amazed at how few raccoons I’ve had since removing over a dozen last winter/spring ...
I fed corn to yard deer all winter, and have a big mulberry tree next to the coop.., so I know I’m “creating my own problems” in this regard ... but the raccoons have stayed away... can’t quite figure it out

... maybe they’ve been warning each other on raccoon facebook or something?
But I totally agree with keeping the numbers as low as you can...
I’ve gotta Coopers hawk that’s been getting fat off the mourning doves in the yard all winter and now I keep seeing it by my coop/run watching the chickens...
I haven’t seen it go after them ... but I think it’s tried because I’ve seen them acting stressed a couple times.... but I’ve gotta plan
I’m always amazed at the way some folks let their birds get terrorized by chicken eaters... but give those critters special “sentient being” status... apparently the chickens don’t rate as “sentient beings”
