Yes, you did get a great deal. I would sell you one of my RIRs for that price. You couldn't touch one of my araucana hens for that though. I have hatchery stock that takes care of my family just fine and then I have others that I had to pay a bit more for and look at slightly harder to find places for. Thats another story. But I am not going to insult people for doing what I have done, without apology, for years.
If it has feathers, clucks, crows, scratches and surrounds you everytime you go in with food, I would say its a chicken.
