My Naragansett Tom is 6 years old and I have two Naragansett hens that are about 8 years old and still laying eggs and setting nests. Since my Tom is a very lovable pet, I hope to find out that they live a very long time.
If you've got a broad breasted your will be lucky to get a couple years out of a tom and another year or two out of a hen. They just grow so fast that their legs and circulatory system can't keep up.
