Ewe lambs born in March and April are excellent candidates to be used as replacement ewes in spring-lambing flocks. With proper feeding and breeding management, spring-born ewe lambs should be in production by the time they are 12 to 14 months of age.
Proper management of the flock at key times of the production cycle can reduce young lamb mortality. A realistic goal of 10% lamb mortality is attainable by most producers.
