About half of my flock contains birds over 4 years old. Most of mine seem to make it to 8 or 9. I have an old one-eyed sussex with no leg scales, and missing 1/2 a toe (Due to her previous owners neglect of scaley leg mite) that I think is between 7-9 years old. She was elderly when I found her, and I've had her for about 3 years. I have heard that they can live into thier twenties, but none of mine have lived that long. Also, does anyone know if bantams are more long lived? Like little dogs live longer than big ones?
