Hello, I am new to this site & new to the whole duck thing, I have a 5 1/2 wk old Khaki Campbell, & just noticed some blood on her where she has been preening near one of her wings...is this because she is nipping herself too hard? or is there something more serious wrong? I have also noticed the last few days it's like she has left 'dandruff' on the floor after preening, is this normal? (her feathers are starting to come through in different spots) I have so much to learn so any help would be appreciated, thank you in advance!
