I've gotten hold of a small 60g pack of Flubenvet wormer, and whilst the instructions are very detailed on the dosage required, I can't find anything on how often the birds should be treated?
This is a precautionary measure, as we've seen no sign of worms. However, our birds are kept in a permanent run, so are on the same ground the whole time unfortunately.
Any idea how often we should repeat the treatment?
Cheers!
