My Speckled Sussex had coccidiosis when she was about 6 weeks old. I treated her with Corrid & she got well. She was slower to develop growth-wise than my other hens, but was thriving& grew into a beautiful, normal weight & size, healthy looking & healthy acting girl . She always ate & drank well & was very chatty & busy in the coop. She started laying eggs when she was about 8 months old & laid well - about 5-6 eggs a week. Yesterday morning I found her dead in the henhouse for no apparent reason. She had been acting fine & showed no signs of illness or stress at all. Could her early bout with coccidiosis have shortened her life like this? What is the life expectancy for a chicken that has survived a bout of coccidiosis?
