My goat Dizzy is due to give birth either tomorrow or the 29th January. She came back into heat after she was bred, and the lady that I got them from thinks that it was a false heat, but re-bred her just to be sure. She looks big, but I wouldn't say she looks enormous. Her udder started to fill this week, but it isn't very tight or shiny. This morning she has milk. Do goats have milk for a while before giving birth, or is it a good sign that she'll kid tomorrow?
