sorry SfS, I don't agree with feeding up to 15 lambs off two feeders, too much competition, I know in theory everything should be calm and each lamb will queue to get milk but weaker smaller lambs will get knocked off just because they are sucking and the other lambs want to play the same game. we now split the pens up so bigger older lambs are one side and younger weaker lambs on the other with two teats either side
