My noisiest chicken is definatly my speckled sussex pullet that is 22 weeks old. She walks around day and night squawking and needs to be heard! Second place is my beautiful rhode island red that is a great layer. My SS is also one of the sweetest and nicest birds in my flock as well! My SS will sing the egg song every time someone else is in the nest laying an egg! This will alert me there is an egg to collect soon! I love it. Which breed in your flock likes to be heard the most?
