Got a month old calf that we are trying to graft on a cow. Been a week now and the cow doesn't kick at all if we put her in a headgate. We keep them separate except for when we are letting the calf suck. Tried to feed her loose in a pen and let the calf suck but she kicks and bunts at the calf when she isn't in a headgate. Anybody with any experience or ideas would be appreciated.
