How the fuck would a medieval duck be any different than a modern duck? Just drop your head lower real quick so it doesn’t get hit. What were the medievals doing, dancing around a fucking maypole, dropping their heads in time to an expertly played harpsichord? smfh

Waddeling on a branch with a pat pat of my feet, the wind in my feathers, autumn leaves twirling in the breeze. Life is good. Excellent duck.

It is also my headcanon that the guy was done and a child came up and doodled a duck onto the page

Honestly looks like it, since it's not been inked! There's someone who sneaks into the monastery at night and adds ducks to all their new manuscripts.

Back then the quack hadn’t been standardized and so this lil buddy may have made any number of duck noises lost to antiquity

These ducks are the marks left behind by the ghost of St Cuthbert - patron saint of ducks - as he does battle defending the manuscripts against Titivillus. The demon goes to insert errors into the script, sees a misplaced duck, and thinks to itself 'drat, someone has beat me to it'

It would be downright heretical to ink over such a blessed addition to the manuscript
