If you want to submit samples to the vaccine research at the Royal Veterinary College, London read on. I regret that James and his colleagues will be unable to help you with more general chicken matters.
Any samples sent through the post must be very securely wrapped to ensure there is no likelihood of escape in the postal system.
Collect you samples in a ziplock plastic bag (4 x 6 inches). Place a little paper towel in with the mites to collect any excess moisture and give them somewhere to hide. Seal the bag with selotape making sure that there are no mites on the outside.
Place this bag in another plastic bag and seal with selotape again. Place this inside a padded envelope.
Send to James Pritchard, Room 121, Clinical Block, royal Veterinary college Hawkshead Campus, North Mymms, Hatfield, Herts. AL9 7TA.
Take this to the Post Office to ensure that the correct postage is applied. Remember that postage charges are based on a combination of weight and size of package.
For further information on red mite see my article in Practical Poultry Issue 123 / April 2014 page 58.
