How can i tell the difference between a black australorp and a black orpington? I just bought a black pullet from a guy who said he got a bunch of different chicks from a hatchery--so he doesn't know what they are. I am guessing that she is either a black sex-linked or black australorp? How to tell the difference between the 3? my camera isn't working, so no pictures. I am just curious how to tell the difference between them. she is the sweetest pullet.
