I only treat when worms are detected however I do one drop all my birds prior to pairing mainly to keep them free from tics and external parasites this also worms them . Treating to get false form has been done for years however the pay back isn't worth it .
See if you can find a old Transfer this will have your granddads loft number on it , then get intouch with R.P.R.A and get a formation of partnership paper then fill it out put deceased next to your grand fathers name when you get the partnership name back all birds rings will be on a print out job done If you get stuck , get a bird and send Gill purser ring number Stating you don't want to report it just get the loft number any problems and I'll help you out good luck mate
