Hello from Southampton, Hampshire, UK Found this great forum due to investigating a louse infestation of one chook - is that an odd thing, just the one hen? I have a three year old Warren who became listless. On checking her I found lice and clumps of eggs near her vent. Since then I have bathed her and thoroughly blow dried her. Her comb went blue for two days from the shock which concerned me! Now using powder containing citriodiol since bathing her did not seem to be effective. I only have the two chooks so do not have a great deal of experience. They are on shavings which are changed weekly and I use a blow torch on the wood to kill mites. Any advice on best practices will be gratefully received.
