One common theme might be the exploration of the relationships between the characters. Since it's a series, the fanfic writers may focus on deepening the bonds or resolving conflicts between the characters we already know from the original.
I haven't read much of the 'Bonanza Bread and Blood Series Fanfic' myself. However, you could also check out fanfic communities on Reddit. Sometimes, fellow fans share their favorite fanfics or even write their own. Just search for the relevant subreddit and see what you can find.
Since I'm not familiar with specific 'bonanza oxbow encounter fanfic', but generally in fanfics, themes of friendship, adventure, and discovery could be common. Maybe in this case, the encounter at the oxbow in the bonanza setting could lead to new friendships or some sort of adventure that the characters embark on.
Love and loyalty are common themes. Since blood binding often creates a strong connection between characters, it becomes a basis for deep love and unwavering loyalty. For example, characters might be willing to sacrifice a great deal for the one they are blood - bound to.
Power is a common theme. Princes in these fanfics often struggle with the power they have or are trying to gain power. Another is loyalty, whether it's loyalty to the family, the kingdom or friends. And love also plays a role, like a romantic love that might change the prince's path.

Another theme is redemption. Many stories focus on characters seeking to redeem themselves from the dark and bloody situations they are in. And survival is also a key theme, as they fight to survive within this harsh and often violent world of the 'cage of blood'.

In Bonanza Little Joe fanfiction, a frequent theme is love and romance. Writers might pair him with an original character or with a character from the show in different romantic storylines.

For example, he might face a difficult moral choice and grow from it. Sometimes, fanfictions also focus on the theme of loyalty, whether it's his loyalty to his family, friends, or the ranch.
