Age makes a lot of difference. You may have two roosters depending on that. Welcome to Backyard chickens. You could post your photo at "what breed or gender is this." but please state the age they are in the photo.
Welcome to BYC! Glad you decided to join our flock. I agree with Mountain Peeps. They all look like pullets to me as well. But if you want another opinion, definitely post on our What Breed or Gender is This? section at https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this and let our experts there take a look at them. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your flock.
