I have some 2 &1/2 week chicks, I also have BO's and blk Australorps. I too have found that the blk australorps are very friendly especially my supposed one cockeral (they marked him), but so are my BO's. In fact I have one BO(they are all supposed to be pullets) that is so friendly that when I go to feed them I have to get inside their big brooder box w/them and she will jump up on me every time.
