Hahahha. Choking the chicken in the shower can result in drain clogging. Hair usually got shower drain trap. U should just keep pouring boiling water down the drain. if u want a better solution u could try this.

Add 3 cups of baking soda + 2 cups of mayonnaise. stir till everything is mixed. then remove the shower drain trap n put the mixture in the drain pipe and leave 4 10 minutes. Then wash down with hot water. Confirm gone.
