I moved last month from Nevada to Oregon. I brought just my one minimancha doe that my son bottle fed with me I just recently got a couple mini Nubians (not really that mini), but my goat loves her grain ration, and the person I got the new girls from says they always loved there's too- but I can't get them to touch it. Thy eat leaves and shrubs on my property but seem to have 0 interest in hay or grain. Is it just because I have so much brush and grass for them to eat (23 acres) , or should I be worried? Thanks!!
