Here are my two Cayugas "Dandy & Mandy"
They are 8 years old, Mandy the female started turning white within one year. Dandy though is gleaming with his true Cayuga beauty of brilliant colors of green, black, and purple. Just happens to females only it appears, but no matter my Mandy is still gorgeous to me. Love them to no end
