Strain improved at the Borowina farm. Starting material were national ducks crossed with Pekin ducks imported from the eastern Germany (former NRD). Then they were placed as a reserve strain at the Agricutural Experimental Station Jurczyce belonging to Jagiellonski University in Cracow. In the following years the flock was kept in one conservation flock at the Agricultural Experimental Station in Szczodre, belonging to Agricultural Academy in Wroclaw. The next step was to transfer this strain on a private farm in Nieciszów near Oleśnica in the lower Silesia province.
