The village was founded as part of the colonization of the eastern territories of the Teutonic Order state. In 1415, Grand Master Michał Küchmeister issued privileges for Marcin Jeschke, Marcin Ressin and Marek Polann for service goods in the Keytemedian forest on Lake Ryn. In recognition of their faithful service, they received ten fiefs under Magdeburg Law, with the obligation to provide one armed service. The lack of a free zone seems to prove that these areas were inhabited by the Prussian population. In the first half of the 16th century it was a free village in which 12 peasants had two fields. In 1488, next to the village, a 10-łan estate was established, which was granted by the Grand Master Marcin Truschess von Wetzhausen to Miśek and Jerzy Pirogi under the Chełmno law with the obligation of one armed service. In the 17th century, this property belonged to the Polish noble Gardliński family. Both the village and the estate suffered severely during the great plague epidemic in the early 18th century; as many as 19 fiefs lay fallow here. In 1816, it was owned by 26 peasants, a blacksmith and a teacher. Wejdyki belonged to the Evangelical parish in Ryn.
A school in the village was established in 1742. After World War II, it was reopened on September 1, 1947, but in 1964 it was closed due to the small number of students.
In 1970, Wejdyki had 35 residential buildings; There was a common room, a cinema room with 40 seats, a sports field, and an agricultural club. In the years 1954–1972 the village was part of the Ryn community.
