My bottle lambs (just over two weeks, and small triplets, both 2kgs at birth) currently get 1.5ltrs goatsmilk per day, 6x250ml feeds. I am now increasing it to 1.8ltrs. But in comparison to my goatkids (same age), they are already much more interested in hay and as soon as I get lamb feed (my merchants has run out!!! at this time of year!) they will get some of that. I can see that they could be ready to be weaned by 6 weeks, but I think I will do it by weight rather than just age. ( BUT If I had to buy Lamlac I would wean them as early as possible/sensible and healthy for them).
