I've had chickens for 3 years. I bought 6 day-old chicks three years ago from TSC. These 6 chicks consisted of 2 Black Sex Links, 2 Golden Sex Links, and 2 Rhode Island Reds. Three years later, I have 1 Black Sex Link, 1 Golden Sex Link, and 1 Rhode Island Red. The first one died at 1 year; another at 2 years, and another at 2 1/2 years. I believe that the first one might have fallen off the roost in a freak accident, but I believe that the other 2 died of being egg bound. I have a friend that also bought chickens 3 years ago and she had an even higher percentage of chickens die than I did. My question is whether there are any breeds that would be reliable layers and have better longevity?
