Just roll your eyes, and say< "seriously? I raise/have ducks, they have toenails...duh, don't live in a fluffy girl bubble..." I am a grandmother...but , it just sounds like naive people with limited information. ....If you want to prove it , take a closeup of your ducks feet and toes ... I bruise easy, just little bumps, all my life, I always have half a dozen on me, as a child I remember them saying "how did you get all those brusies on your shins...?"duh...."I don't know, playing" (this was 50-60's before the cutting fad). My mother also brusied easy, my daughter and one son does too. One day I was at the dr. and he said ," you have a bruise"....I burst out laughing.... "no my husband doesn't beat me, I am like, half hemophiliac ...if I don't have a half dozen bruises on me ,it's unusual., been this way all my life.... He then looked at my skin and said, "oh, you are missing a fat layer under your skin..."(you can easily see my veins and arteries). Which may also be why heat doesn't bother me and I freeze before anyone else...
I have gotten scratches from working with raspberries, fencing, my ducks and geese, cutting privetts and brush.....if anyone says anything , I just say ...."I have a farm, animals and I work outside a lot"
