I have three Olive egger Chicks weeks old. Can anyone tell their gender for me? They are about 4 1/2 weeks old and a cross between EE and Black copper Maran. Thanks for your help. This is Sharpie. This one is Olive. This one is peaches. She is the only one with feathers on her feet. I just need to know, because I can not keep a Roo. Thanks.
