Not in the porch

We have been caring for a friend's three baby chicks. They have pooped a bit in our front porch as chickens sometimes do. Fiona, who has a bad relationship with poo states that the chickens are naughty. I, in embracing bodily functions as normal for all animals say, it's not naughty to poo..Fiona digresses, "well it is naughty to poo in the porch!"
