Hi, I'm new to BYC. I just got a couple of chicks off of someone down the street to add to my flock. I was wandering what breed they are. All he told me was that they are brown pullets...so does anyone have any ideas as to what breed they are..here's a couple pics of one

It is extremely hard to try and guess the breed at this age, I would post again when they have feathers.
