I've treated my roo x2 for lice (two weeks apart) and haven't seen any creepy crawlies since. He does, however, still have the egg clusters at the base of his feathers (around his vent) Should I pluck the feathers? This seems like it would hurt but should it be done? Could I put some vasteline over it if I do need to pluck? Any help or opinions would be greatly appreciated! ETA: I treated with garden and poultry dust, active ingredient is permetherin.
