hello, i have 4 scovy ducklings that are about 5 weeks old. i noticed that they are all picking at eachothers wing feathers that are coming in. one of them is even bleading from the tips is there anything i can do to stop this? i thought about separating them but it's not just one duck, they are all doing it to everyone, plus they HATE being apart and freak out. i don't know what to do and hate seeing poor scooter bleading any suggestions?
