I got half a dozen chicks at tractor and supply recently and we forgot to ask what breeds we got! We think the black ones (the first picture) is a barred rock since it has a white dot on it's head and the feathers on its wings look similar to that of a barred rock. Now the picture of the white ones (Second picture) is the breed that we have no idea what it is. It's most likely a pretty common breed since its from TAS, but who knows. IF anyone thinks they know what the breeds are feel free to comment and ask if you want some more pictures. Thanks!
