I know this topic has been done to death, so sorry in advance. I was planning to scrub the legs with warm water and a toothbrush, then apply vaseline daily. Is there anything I may have at home which I can mix with it or use instead which could help? I am about to give the coop a scrub and a dusting with DE and also put some in their dirt bath. I also have 'Advantage' (Imidacloprid 100g/L), would this assist? Many thanks!
