One thing worth knowing
This treats several conditions at once rather than diagnosing which one your birds actually have — Harkers' guidance covers dosing and timing, not how to tell canker from coccidiosis, so if you're unsure what you're dealing with, an avian vet is the better first call.
Why we chose it
It treats the whole loft through the shared water rather than needing each bird caught and dosed individually, which is the only realistic way to medicate a flock. A named brand with a clear syringe-measured dose is worth the small premium over an unbranded soluble.
— Matt, founder
Full description
A racing pigeon loft shares one water supply, which is exactly why a liquid added to the drinker treats the whole flock at once rather than needing each bird handled individually.
Harkers 4 in 1 Soluble is a liquid treatment for canker, coccidiosis, worms and external parasites in racing pigeons, using the dosing syringe supplied. The manufacturer's own instruction is 6.0ml added to 1 litre of fresh drinking water, given daily for 5 days, with fresh solution made up each day and no other water source available to the birds during treatment.
- Treats canker, coccidiosis, worms and external parasites
- Harkers' own dosing: 6.0ml to 1 litre of water, daily for 5 days
- Contains Amprolium Hydrochloride 3.8% w/v, Ronidazole 1.2% w/v and Ivermectin 0.0266%
- 100ml bottle, described as sufficient for 50 birds
- Not for birds under 8 weeks old
- Harkers advise repeat treatment every 6-8 weeks or when infection is suspected
One thing worth knowing. This treats several conditions at once rather than diagnosing which one your birds actually have — Harkers' guidance covers dosing and timing, not how to tell canker from coccidiosis, so if you're unsure what you're dealing with, an avian vet is the better first call.
Who it's for: pigeon keepers running a routine flock health programme, particularly ahead of breeding or racing, following Harkers' own treatment schedule.
