About this life stage
A typical Sheep moves from lamb (0-1 yr) through hogget (1-2 yr) into adult (2-7 yr) and senior (7-15 yr). The lamb year compresses immune-system development and rumen maturation; weaning stress in this window has lifelong implications for parasitic susceptibility. Adult years are when wool, milk, or companionship roles stabilise. Senior signs arrive around year 8 — molars grinding down, slower flock pace, increased need for shelter from cold rain.
