I have 6 different breeds of chickens I have a a RIR,Black Australorp,New Hampshire Red,Red Star,Buff Orpingtonand a Blue Andulusian but I know she lays white eggs but the thing I am wondering about is I have one that lays a real big egg and I thought it was my RIR and I really don't know if someone could help me find out which chicken is laying which egg I would really like it very much thank you.
