Grooming Lucy shedding a LOT

[LithiumRiot]

So my oldest pig, Lucy, has recently started shedding a lot. Like i will be petting her and bunches of fur will fall off her. She doesn't seem to have any bald patches or anything but i've had her for well over a year and this has never happened. Any reasoning why this might be happening now?

Are there specific areas where her hair is falling out? Or is it all over?
