If your target show is in March and you are just now starting to work your goats, then you are behind. The ones that are planning on winning have already been doing their work. Practicing showing, exercising, working hair, managing feed/weight, etc. You can’t win a show in March by working Jan-March. It started last fall.
The thing I like about doe shows, is it is easy to tell who has consistently been working hair and who started a week or two before their local. Working hair on a doe a couple of times a week will pay off. The hair will “pop” more, lay right and therefore, be easier to clip properly.
