I currently have four cows in my Harvest Moon game. One is a male, and the other three are just the normal type of female cows. The first cow the game starts you out with lets me milk it, but for some reason the other two cows (my original cow gave birth to) whenever I try and milk them they just have a black question mark over their head. This has been going on for about four seasons in Harvest Moon time. So my question is, how can I start to get milk from these two female cows?
