What can I do to make my chickens quiet?

[Tigerkid]

We worried about the chicken noises bothering the neighbors, until we realized all the neighbors had chickens, but we didn't really ever hear any chicken noise over the sound of the neighbors dog barking.

We had chickens a year or two ago, but then a neighbor complained. We thought they didn't like the rooster so I sadly agreed to kill it, then about two months later the HOA (Homeowners Association) told us that we couldn't keep the hens because they sang the 'I LAID AN EGG!! COME LOOK!!' song. We gave them away to a farmer and after around 3-4 months we got bad news. One was taken by a coyote and one got a throat obstruction. Both died. I've never felt so much sadness in my years of life.
