Hi there. Well my (hopefully) girls are about 7 weeks old now and I'm wondering about the breeds. The hatchery from where the eggs came, stock Australorp, New Hampshire Sussex, B + W Leghorns and Lohmann / Isa Browns. I'm thinking the black one could be an Australorp? No idea about the white one as I haven't been able to find any pics of chooks that look like (hopefully) her. I don't know why the black one always looks so angry. She's the more affectionate and likes nothing better than to sit on my shoulder.
