My experience with golden sex links leads me to say avoid them. Oviduct cancer and prolapse was common. I haven't been around Black Sex links for more than 30 years, so I don't know what others are experiencing. I've had healthy layers of the Australorp breed and mine is going on 7 yrs. now. Sex links lay much in a short period of time, but to see them with so many health issues and short lives has caused me to avoid them.
