I got straight run chicks from the local ag store last March. I did not write down the breeds I purchased because I believed the worker would have written them down on some kind of receipt (which he did not). I got like 3 of different kinds for a total of 24. Now, I have figured out most of the breeds I have but am still at a loss on my black hens. There are two black roosters and four or five hens. The roosters I feel confident are Jersey Giants. They are huge and have glossy green on their feathers. However, is there some way to tell the Australop hens from the Jersey Giant hens? I can take photos if necessary but don't have any good ones right now. These are the only two black-feathered breeds that this particular ag store carries.
