1. Start by breeding two white sheep. You can do this by dragging one sheep onto another in your pasture.
2. The resulting offspring will be a lamb that is either white or black. If you get a black lamb, you're on your way! If you get a white lamb, simply repeat step 1 until you get a black lamb.
3. Once you have a black lamb, you can breed it with another black lamb to produce more black sheep.
4. Continue to breed black sheep until you have enough to complete the mission.
Here are a few tips for breeding black sheep in Tiny Farm:
* Use the "Selective Breeding" feature. This feature allows you to choose the traits of the parents that you want to pass on to their offspring. By using this feature, you can increase your chances of getting black lambs.
* Breed your sheep in a separate pasture. This will help to prevent them from breeding with other animals, which could produce offspring with different traits.
* Be patient. It may take some time to breed enough black sheep to complete the mission. Just keep at it and eventually you'll reach your goal!
Once you have completed the mission, you will be rewarded with a special animal that will help you on your farm.
