When raising puppies for LGD work there are "rules". From our experience here is what we find works best. (We have broken a rule occasionally and still had great results BUT the more rules you break the more chance of failure).
We raise your puppies with bottle fed lambs & goats, poultry and rabbits when young in their pen, soon they are roaming the farm with calves, cattle and horses.
We give just enough human time that they are not afraid of us and will come around us when we call. Attention given to mom (& moms reactions to us) teach them that humans are OK. As they grow and depend less on mom for meals (and more on us) they learn that we will care for and feed them.
Too much attention early on and they WILL kill your livestock. We have experienced that several times when we started out. In the beginning we purchased several "LGD" breed dogs from various sources, and turned them lose on our farm where they killed many of our animals. Finally we acquired our current LGD's as pups and raised them properly with no more problems from bad dogs or predators. We have found a good balance of human time.
Around 6-7 weeks they are really exploring their environment. Week 8 or 9 they start to "patrol" the barn yard with mom and initiate play fighting to build survival skills they will need very soon. A week or two later they start to expand their patrols to the entire farm. Being in a pack for several more months is essential to their survival when attacked by a serious predator often a fight to the death of one of them. For a LGD, time in the pack till six months of age is crucial to its survival. (8 months is best but more is not much better). This time is also when they learn moms methods of protecting their charges.
