Our large white girl has a dirty vent
and is losing the feathers rapidly around that area. Could anyone shed some light on this please?

It is the time of year when many chickens molt and that could be the reason for feather loss. Other causes for a dirty bottom include worms/parasites. Dawg53 has some wonderful info on worming and I know that one wormer should not be used during molt because it can cause stunted feather growth. I can't remember which one that is. Type worming chickens into the search bar and you will find a wealth of information. Mites/lice don't cause dirty butts.
