In the UK, most lambing occurs during March and April, but some ewes may be scheduled to lamb as early as mid December, all the way through to June. Again, this depends on the breed, environment and stock management.
Lambing is the busiest time of year for sheep farmers, as someone needs to be on hand day and night to ensure there are no lambing problems. Most ewes give birth with little problem, but occasionally a farmer may need to help, especially if the lamb is coming out backwards.
It is vital that lambs and their mothers are given time to bond, so they will often be moved to an individual pen if they are lambing indoors. During the first few hours, a lamb will have their first feed of colostrum (a thick milk produced by the ewe that is packed with nutrients and antibodies to help the young lamb grow), and will be quickly up on their feet bouncing around!
Ewes and their lambs will be turned out to the fields as young as possible, as they thrive best in open space with plenty of grass. Depending on conditions, this can be within as little as 12 hours from birth.
