I have a dummy calf which I have been bottle feeding since birth - now three weeks old. Mom very protective, but wouldn't let calf nurse nor let us help. Low and behold, yesterday we saw the calf nurse. Checked quickly and she does have milk. Question - should I continue supplementing with a bottle, or just let the calf build up moms supply again? Calf healthy and big - not scrawny at all - just real dumb.
