It doesn't change anything.
I was playing my COC like every morning when i suddently realized that there was something green in my dragons lv 2 wings,i thought "I 've never seen this,maybe i'm just dumb enough to never Have looked at it".
Then (i was playing on Ipad) i zoomed in and saw that the green things on the dragons wings where the ground and then they moved to the camp and that "thing" turned brown because they were above a giant.
Conclusion: there's a bug/glitch where the wings should be attached to the dragon, which make that place invisible or transparent.

I'm new to the forum so i don't know if you guys have already posted something like this so, if you do, i'm really sorry.
Thank you for reading and good game for you!
