The 10 commandments of breeding:
1) Breed toward your ideal shetland sheep. Don't be swayed by the negative voices of others. If you have done your homework, in time others will appreciate what you have accomplished.
2) Recognize that you are breeding shetland sheep and stay within your interpretation of the breed standard.
3) Never forget: No hoof, no sheep.
4) Always strive toward a sound sheep that can be of good use, plus beauty. Neither is good without the other.
5) The next generation need not be similar in phenotype to the generation before, but each generation must be consistent or an improvement in overall quality than the generation before.
6) Breed forward, look ahead. Wonderful new suprises may be awaiting you. Recognize them when they occur.
7) It is not difficult to improve the produce of a poor quality ewe in one generation. It is not even difficult to improve the produce of an average ewe in one generation. What is difficult is to improve the produce of an exceptional ewe generation after generation. That takes real skill, knowledge, gut instinct, and vision.
8) Don't be afraid to appreciate the qualities of another's flock. Breeding is a competition with yourself, not with others.
9) Don't be envious of another shepherd because they thought of something you didn't think of, discovered something you didn't, or are unencumbered by the limitations you have set for yourself.
Wish I could remember where I saw this orginally so I could give the writer credit. I know it was from a horse site. I changed it up a little bit. :)
