3 of my white rock hens cluck/crow on a daily basis throughout the day?

[Katelyn11]

All of my chickens lay eggs (im pretty sure) as when i bought them from a nearby farm i was told they were females but i would have to wait it out to be sure. But they would mostly likely be females, but everyday at least 3 of my chickens crow/cluck very very loudly. i have no idea how to stop it as i live in a residential area with houses just over the fence which is not far at all from their pens and run. They roam around my backyard but every morning (at about 4-5 am) i find my self out side unlocking them for the da already as they were making a racket from crowing. Can someone give me some nsight as to what is wrong with my hens please. i have 1 rhode island red and 5 white rocks.

You might want to post pictures of your chickens on the What Breed Or Gender Is This board, sounds like you might have a couple of roosters. https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this
