Hi and welcome to BYC - great that you have joined us. Sorry, at such a young age I'm not sure most members could help identify the breed. Maybe when they begin to develop feathers, you could post on the gender / breed ID forum - https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this
Your little ones are adorable! I agree that the Breed or Gender Forum will be your best bet when they are a bit older.
I hope you enjoy being a BYC member. There are lots of friendly and very helpful folks here so not only is it overflowing with useful information it is also a great place to make friends and have some fun. Unlike non chicken loving friends, family and colleagues, BYC’ers never tire of stories or pictures that feature our feathered and non feathered friends
