Good mothering ability is a characteristic of a good Shetland ewe.  Twins are quite common for Shetland ewes.  Singles or triplets are also seen. Very occasionally, natural quadruplets are produced.  Only very growthy ewe lambs should be considered for breeding the first fall. Bear in mind that ewe lambs are not finished growing themselves. Some feel that bred ewe lambs may not reach their full growth potential so future productivity may be compromised.   While ewe lambs usually prove to be good mothers, lambing out ewe lambs requires a bit more vigilance and skill.  If you are a new shepherd you may want to begin lambing with experienced ewes.

The average Shetland lamb weighs 4-7 lbs at birth.  Singles tend to be larger.  Twins and triplets may be smaller
The total weight of all lambs in the litter is commonly 10-15 lbs
The largest Shetland lamb I am aware of weighed 11 lbs as a single. 
The smallest Shetland lamb I've known to survive, with some help, was 2 lbs.

The gestation period for Shetland ewes is typically 145-147 days. 

For a quick lambing start date estimate,  take your first date of ram exposure:
add 5 months then subtract 5 days.


Rams in 10 November 
Add 5 months which brings you to 10 April
Subtract 5 days
Expect lambing to begin 5 April

Be sure to record the days you put the rams in and when you removed them.  Also note carefully in your calendar any accidental exposures of ewes to rams.  If a ram should get in with your ewes early, chances are a ewe or two will have been bred and will lamb early. Make a second note to repair or change your pens to avoid this mishap in the future.

Be prepared for lambs a few days prior to the earliest expected date.  The more ewes you have to lamb, the better prepared you should be!

Successful lambing depends largely on the management of your ewes before lambing.

Ewes need free choice access to salt and fresh mineral mix suited to your area.

Ewes should not be too thin.  They need good nutrition to grow healthy lambs and to stay healthy and grow a good fleece as well as good lambs. See

Ewes should not be too fat.   Over conditioned ewes are more likely to run into problems delivering their lambs. Don’t over feed the ewes in the last 3 weeks or so of pregnancy as the lambs can get too large.  This again can create more difficulty in delivery.  This puts the health of the lamb and ewe at risk.  See Condition Scoring your ewes.

A sensible feeding program that takes into account the nutritional requirements of the ewe at various stages of gestation, lactation, maintenance and flushing is needed. You need to know the quality of your feed and how much to feed.  Remember that as the lambs take up more space inside the ewe, there is less space for food in the rumen.  As pregnancy progresses, the ewe may benefit from more frequent feedings and or higher quality feed to get the nutrition she needs. See Feed for further discussion.

Pregnant ewes need lots of exercise.  A strong, healthy ewe will deliver lambs without undue stress and will be active in mothering the lambs right after delivery. As much as your farm property will allow, get your ewes out walking all year long, especially when they are pregnant. Consider placing feed as far away from the water and shelter as you can. 

Shearing considerations
On the Shetland Islands and on mainland UK, it is common to shear the ewes after lambing. The advantages are that the ewe retains protection from the elements.  The lambs can snuggle into the fleece for warmth.  The fleece is well risen and the sheep can be rooed or hand clipped more easily at that time.

In North America it is more commonplace to shear the ewes about one month before lambing.  Occasionally the stress of shearing will cause a ewe to deliver her lambs prematurely so it is best to handle ewes gently and not shear too close to lambing dates.  3- 4 weeks prior to lambing is good.  It is easier for the shepherd to observe the udder and the birth process when the ewe is shorn.  It is thought to be easier for the lamb to find the teat to nurse.  Shearing before lambing means that the fleece remains cleaner.  

Another option is to ‘crutch’ the ewes.  This means clipping only the wool from the udder and around the hind end.

Vaccinations and Worming
Discuss a plan with your vet.  Local worm and disease populations do vary. 
Vaccination of ewes 4 weeks before lambing ensures that lambs are protected through the colostrum or first milk they receive from the ewe. If you are shearing ewes before lambing you can vaccinate and trim hooves at that time.

Consider worming your ewes at lambing time. There is a natural rise in worm load in the ewe at lambing as more eggs are laid with the onset of warm weather. This is known as the periparturient rise.  Keeping the lambing area free of worms will help keep your lambs healthy and growing well.  You can worm the ewes before or after lambing.  If using jugs for lambing, worm the ewe in the jug or as she leaves the barn with her lambs.
