Langdon, its not right to have an overweight goat at any time, and I can see you are concerned about your goats being overweight before going to the billy. But, over the years, I have had goats of all shapes and sizes ....never weighed any of them before going to the billy, and they all got in kid whatever their size. So, do not worry too much. Now they are on a diet, they will be the right size by Autumn - honestly!!!
