do you guys leave the grit inside the loft all the time and what do you use to put the grit in?

Yes, I leave the grit inside their "dining" room. I replace it constantly as it is emptied.

I either use the pick pots the grit comes in, or use a plastic feeder that has a top over it. with holes in the side so the birds can stick their heads in to eat it. Sometimes they make a big mess with the open top grit/pick pots. The pick pots are better used for small number of birds.
