For the most part hens are very quiet and make a low sweet contented cluck cluck. They also make a sort of song (or noise depending on how you look at it, lol) when they have laid an egg, though I have seen them make this same song if you will even when they haven't laid an egg. When they see you coming with food they often "talk" all excitedly about what goodies you've brought them. Some are just more vocal then others, like my Emma. But sometimes they can really and I do mean REALLY make some dreadfully loud noises. Usually one starts and others join in and it is loud! This is one reason I suggest NOT getting chickens if you are not allowed to have them. They are not quiet all the time and it only takes one upset neighbor to turn you in if they know you're not supposed to have them.
It is actually much much louder in person! I have had several of them go on like this for an hour! This time it all started with several fighting for the same next box even though I had 3 other available. Two fighting for a spot behind the door even! Crazy chickens! There are quieter breeds of which Rhode Island Reds and Barred Rocks are not part of. They are very vocal hens. The Easter Eggers (Amerucana mix) are pretty quiet docile hens. The one in the nest box kept getting bullied out of her box by the Emma the Barred Rock standin next to her. I love most of there noises but when they start in like this they really drive me crazy! The only way to finally shut them up after an hour of carrying on was to throw some scratch in the run and most of them flew out and happily and quietly ate it then settled down after awhile back to there peaceful and contented state and the others to lay their eggs in peace.
