Were they dam raised or bottled? Worming or cocci treatment history. Need to think about if these does are going to be for breeding purposes. Did the dams not have enough milk or are the mothering skills not up to par to produce a healthy kid? They should be decent size by now. Just my thoughts.
When I bought them i was told that they were Dam raised (saw their dams and they were very nice goats.),had been wormed,I don't know about cocci treatment/prevention.I think I'm going to call the person I bought them from.
