Limited Means, Greater Disposal
The battle between the two Monster Gecko groups ended up in a stalemate as the Monster Geckos from the first village retreated into the village in fear of an ambush. As they were just monsters without any sentience, despite their superior physical prowess, they only reacted based on external disturbances, behaving accordingly.
That's why they retreated into their village immediately, not even thinking of any other solutions. Besides, their first instinct was to protect the regular populace that was in the village, the non-fighters.
Based on what Krune had gathered over the past months, the Monster Geckos had non-combatants among their populace. Moreover, non-combatants made up most of their populace. They were in charge of collecting the fruits, harvesting materials for building constructs in their village, making their tools and weapons, giving birth, and so on.
