Creep feeding lambs

These lambs are offered grain, nice leafy alfalfa hay, and fresh water in an area adjacent to their moms hay feeder. The moms cannot enter this area.  The lambs, however, are able to move freely into and out of the creep area.  A creep gate, placed between the two pens, will prevent the ewes from entering the lamb creep pen.  The creep gate has openings that are too small for the ewe to enter, but openings big enough for the lambs to move easily through the gate. 
Lambs are offered a creep area so they will be well on their way to a full grain and hay diet when it is time for them to be weaned.  When lambs are offered grain and alfalfa hay, they will continue to grow and gain weight even though their mom's milk begins to diminish when the lambs are 6 weeks old.
