I appreciate your patience. There are three common reasons why rabbits pull out their own fur. One is to make a nest, whether due to a pregnancy or a false pregnancy. I don't think that is what Flick is doing. They usually pull fur from the neck when that happens.
Boredom, often due to a lack of fibrous food to keep them busy. If you don't already do this, provide unlimited grass hay for Flick.
Finally, irritation or pain in the area can cause a rabbit to bite at itself, pull out fur, and scratch the are if possible. It's impossible for a rabbit to scratch the inside of the hind legs, so biting and fur pulling are more likely there. I suspect that Flick may have a urinary tract problem. When they have such problems, they can't control the flow of urine and it will leak down the inside one or both back legs. The urine dries on the skin, and eventually the ammonia in it even burns the skin. This is called urine scald. Urine leakage can be caused by infection, bladder or kidney stones, diabetes, tumors, kidney disease, or a condition called sludge.
Now that flick is clean, inspect her several times a day. If it looks like there is urine on the legs again, you can be pretty sure she has one of these conditions. In that case, you'll need to see a rabbit vet. This link will take you to a directory of such vets:http://www.rabbit.org/vets/vets.html
Some rabbits do pull out their own fur when they start a normal molt. In that case, you should see new little hairs starting to poke through the skin within a week.
