We traded Mango for these 3 birds. one if definitely an Australorp. The other 2.. well.. we are not sure. They are about 11 weeks old. I am needing to learn their gender and breed. I know it is a lot to ask via internet, but these white birds were supposed to be Cornish X.. and obviously they are not. The friend that I got them from says that if any of them crow, I can return then and we will try to catch a pullet. here goes..... Isn't she cute! Celeste has named her Pearl.. and I love it!!!
