Q: What is Harkers 4 in 1 Soluble used for? A: It treats and prevents canker, coccidiosis, worms (roundworm and hairworm) and external parasites (lice and mites) in racing pigeons, administered via the drinking water.
Q: How is it dosed? A: Add 6ml of the product to 1 litre of fresh drinking water daily, for 5 days, using a freshly-made solution each day and no other water source available to the birds during treatment.
Q: How many birds does one bottle treat? A: One 100ml bottle treats up to 50 birds.
Q: Are there any age or timing restrictions? A: Yes. Do not treat birds younger than 8 weeks of age. Parent stock should be treated 3 weeks prior to breeding, and treatment should be repeated before racing begins and then every 6-8 weeks as a preventative measure.
