Pottzy, they’re super quiet. Just build a coop and go for it. No one will know. 
Great looking door Pottz and I'm almost over the painting of mahogany thing, ha! My city of Calgary has now allowed a finite number of chickens for personal use in backyard coops. Seems to be working so far as long as Foghorn isn't involved in early morning symphonies. :) Cluckingham Palace. I love it!!
