My 5 mth. Old female cayuga started getting white spots about a.month ago and now is walking with a limp. I know the white comes with age but she's only 5 mths. Old. What could it be. What is their life expectancy? I had a large jumbo Peking who started limping and died within a week. Help! I dont want to lose this one. I have checked the bottom of her foot and don't see anything that looks abnormal and pain seems to be in the joint. She stands with thay left foot lifted.
