Holland Lops can have several dozen offspring over the course of their lifetime. Not even professional rabbit raisers will keep all of their bunnies.  If you are raising Holland Lops to show or sell, you need to examine them at six, you can get a good idea of whether they are destined for lives as pets or as show animals when they are six weeks old. At the age of six weeks, a show-quality Holland Lop should have strong, short front legs, with visible space between them. The rabbit should be about as wide as it is tall. When you look at your rabbit from the side, in profile, you should be able to see its ankles. The ears should not extend much lower than your rabbit's chin. They should lay flat. The crown of the head should be as close to the ear as possible. You don't want a lot of space between the ears and the eyes. If a rabbit does not show these characteristics at the age of six weeks, it probably should become a pet, not a breeding stock. Even rabbits that are not show-quality can make great pets. Rabbits for breeding bunnies or taking to shows should show the qualities on which they are judged at six weeks and as they grow up over the next year.
