Harkers 3 in 1 Soluble

Treating a loft rather than one bird is the whole logic of a water additive — every pigeon that drinks gets the same dose without having to be caught and held still, which matters when there are dozens of them and one of you.

Harkers 3 in 1 Soluble is given via the drinking water, and Harkers describe it as tested and approved by racing fanciers. It contains Amprolium Hydrochloride at 3.8% w/v, Levamisole Hydrochloride at 1.7% w/v and Ronidazole at 1.2% w/v, and is intended for the treatment and prevention of coccidiosis, canker and worms. It comes in a 100ml bottle and is only for use with pigeons.

On dosing. We're not printing a mixing rate or a length of course here — Harkers' own bottle carries the exact amount per litre and the number of days to give it, and that's what to follow rather than anything summarised on a shop page. If in doubt, a poultry or avian vet can confirm the right approach for your loft.

Who it's for: pigeon keepers treating a loft rather than a single bird, where a water-based additive is more practical than catching and dosing each bird individually.
