How big are lambs?
Depending on their breed, gender, and nutrition, newborn lambs can weigh around 8-10 pounds. Larger breeds of sheep can produce offspring weighing up to 12 pounds.
Newborn lambs can stand and walk on their own shortly after birth. They would seek their mothers’ udder to feed on their milk.
At 6 to 8 months old, lambs can weigh over 100 pounds. If you’re raising lambs for meat, you sell them as early as 3-5 months.
How long are young sheep considered lambs?
Young sheep are considered lambs from birth up to one year of age, after which they would be considered adult sheep (either a ewe or a ram).
By the time they’ve reach this age, these baby girl and baby boy lambs should have long been weaned from their mothers.
Some sheep, like Babydoll Southdown sheep, stay small until adulthood. Even so, they are no longer called lambs once they reach one year of age.
What color are lambs when they are born?
Lambs can be many colors when they are born. The most common shade is white, but black, brown, and red are other common colors.
It’s possible for a lamb to be born black even if its parents are both white. Some breeds are born with darker colorings that become lighter as they grow into adults.
For instance, California Red lambs are born with red wool. Over time, they fade into more of a brown color.
