Tobi, to answer your question, although I use natural (non-chemical or artificial) treatments where possible, in the case of prevention of blowfly strike I make an exception, as the results of infestation can be appalling. I never had one case in all the time I had a flock, using a simple pour-on treatment. You can read about similar UK equivalents here:

I actually used Butox pour-on, which is a simple "put a few drops on neck and back" treatment, similar to the method used for cats and dogs against fleas (but not the same product, of course!):
