You may still be getting wind effects. Depending on how close/tall your fences are, they may be creating a structural downwash affect in the space between them if the wind is crosswise. (You may learn about them in your fluid mechanics course. BTW, I work mainly in air dispersion/atmospheric modelling, so I'm quite familiar with structurally generated turbulence.) The only sure way to minimize wind effects is to either (1) pick your outdoor ranging day carefully or (2) range indoors in a large/long space.
