Hello everyone! Hoping to get some help & clarity here! I just got 4 adorable little ducklings... pic 'cause I know you all love them!! The duckling I am concerned about is the fluffy little Khaki Campbell. He/she has something on the bottom of both feet. I'm not sure if they are scabs, calluses, the beginnings of bumblefoot already? She/he was a last minute addition to our purchase. That was the last lonely little Khaki in the pen at the store & it broke my heart to leave him/her alone. So I impulsively took it without checking it over... shame on me. (Honestly... I would have taken it anyway!! They certainly wouldn't have helped the duckling out!!) Any way, any thoughts?
