they are both girls and eat a mix of all flock and cracked corn oh and I have had them for 2 weeks
Feather issues can arise when there is a nutrition deficit in the diet. By providing cracked corn in the feed you're effectively diluting down that amount of nutrients there getting. I would feed solely all flock, and maybe start offering greens. If you received them two weeks ago it's possible the previous owner had drakes and created the damage you see. Hopefully, with time it should resolve itself.
