I would be really grateful for some advice with this, as to how to proceed and what I should expect from the school. This happened on Friday lunchtime; apparently the boys did this as some sort of dare. My DD informed the lunchtime supervisor, who I think mismanaged it, by not escalating to the head or informing DD's teacher/TA, and then getting DD to wash it off herself (with bare hands, communal sink which wasn't disinfected afterwards).
I have emailed head, who will be investigating tomorrow. I was wondering what is reasonable to expect. I am trying to remain objective, but there is something particularly horrible about three boys singling out one girl to do this to. It was bird poo, so could have been worse, but still a Salmonella risk. Thanks for reading!
