End of February I purchased 6 chicks from Tractor Supply. I knew they were pullets, but the breeds I was told they were, aren't matching up with pictures I have seen and researched. I am new to chickens, so I am looking for some help! I was told the pullets were either Rhode Island Reds or Barred Rocks. The black chicks had some gray to them, but now appear almost all black. I recently noticed they have some brownish feathers coming in around their necks, and some slight brown on their backs (hard to see from the pictures). They are not looking like barred rocks. Any help to confirm the reds and the breeds of the black would be greatly appreciated!
