Not to offend anyone, but I use the term "cull" here to mean any rabbit that will not be shown, and is to be sold as a pet.
This is how I had my 10 year old daughter cull rabbits, since many of the rabbits she wants to keep for the wrong reasons. This method leaves no questions on whether to keep a rabbit or not. And it will work for any breed.
Make a list of your breed of rabbits 25 "most important qualities". If your not sure, go through your breeds standard of perfection. On my Links page look for your breeds standard on one of the links. Rate each and every rabbit on every one of the 25 qualities. Using a 0-4 scale. 0 is extremely poor and 4 is your ideal (we rated colored rabbits with white or mismatched nails "0" for nail color--which was one of our 25 qualities--we rated dilutes with very dark, matched nails "4" for nail color).
When every quality is rated, add up all 25 scores, and cull any rabbit that gets less than 80 points. This method worked well on all rabbits except our Netherland Dwarf big brood does which has produced grand champions, but on our scale rated for show rabbits-- barely got 75 points--they lost points on ears, weight, condition and color. So we decided to make a "bonus" category--adding 5 points for every grand champion produced in the last year. In this same category, we also deducted 5 points for any tempermental, high strung rabbits. Our Netherland Dwarfs scored between 70 and 96 points. Our Himalayans scored between 76 and 90 points. A good place to create a form for your own breed is the breeds standard of perfection. For every 4 points given to any particular feature, create 1 line for that feature. For example--if 12 points are given for back leg markings create 3 lines for that feature (we used color, definition and markings going high up). Any particular weaknesses yo have in your herd, you should add a little more weight to that feature. We just started using this, and found it hard to judge bunnies under 2 months old, as many of the qualities, were based on adult features (ear length, registration weight, etc...) If you really know how your lines develop, it might be worth making a seperate list for bunnies under 3 months. But if you know your lines that well, then you don't need to go through the qualities that you want in a show rabbit. If you try this, let me know how it works out for you, and any suggestions or alterations that you found helpful.
