These are my chicks they are 1 week old today. The 2 Browns are Aracaunas the yellow was in the brooder with aracaunas, it could be a white arac or a white rock because they were underneath them. Tomorrow I am getting 3 black Giants 3 buff orp 2 each of barred rock and golden laced wyandottes. Hubby & myself are loving this new venture in our life vest and the chicks are such funny little things to watch. If I did the vent test correctly they are all hens.
