Hello! We are new to chicken raising. We have had a flock of six since they were a week old. We are told that the black is an Australorp, that the three white are Australorp,and that the two reds are Isa Brown. We dont know if they are hens or roosters. I would love your opinion if the breeds are correct or if you have an idea of whether they may be hens or roosters! They are about 9 or 10 weeks now and I will try to attach some photos below,. Thanks!!!
