We have just cleaned out the litter tray we use as a dust bath and refilled it with bird sand and louse powder, the girls go mad for it and spend ages in there after a couple of hours it's empty nearly is this normal or have our girls got a really bad lice problem?

No idea - all I know is that mine can dig pretty deep holes when they decide to make a dust bath - would soon empty a litter tray.

To check for lice you would have to physically pick them up and look.  The area under the vent seems to be a favourite place for them to congregate, and if bad you will see clusters of eggs attached to the feather shafts as well as lice moving around (and onto you!).

checked them and can't see a thing they look clean as a whistle think they must just enjoy it!
