I have bins of compost in my garden but they are sludgy and smelly. Can I save them with browns???

Hey everyone,

I’m a home gardener but I’ve been really intimated by making my own compost. I have three FULL compost bins in my back yard, but they are liquid and smelly (most definitely from lack of aeration). I’m not quite sure what to do with them , are they salvageable if I add tons of browns and maybe drill some holes ?
