Ronsec dosage for Canker?

[finnleywren]

I'm going to try Ronsec for what I believe is a case of canker with a resistance to Metronidazole. If it doesn't work I'll assume it's wet pox. Symptoms are a better match for canker so I want to give Ronsec a try. The tablets are for pigeons/raptors and not necessarily recommended for chickens but I'm seeing other people have used it here. I'm not finding a dosage that makes sense. Here are the details from the website:
Ronsec by Medpet, the ultimate single dose treatment for hyper-resistant Trichomoniasis (Crop Canker) in pigeons and raptors.

DESCRIPTION:
- New safe and effective formulation.
- Does not cause regurgitation.
- Contains a combination of 2 extremely safe and effective active ingredients that work synergistically in a special slow release tablet formulation.
- This unique product has been proven to cure 98% of Trichomoniasis cases, even those caused by hyper-resistant strains.
- To prevent resistance it is recommended that Ronsec only be used in cases where other Crop Canker treatments have failed

COMPOSITION:
- Ronidazole 25mg,
- Secnidazole 25mg

USE:
-1Tablet per pigeon after the pigeon has eating and it is full.
- Wait one full day before repeting treatment.

Any advice? It looks like they are advising two tablets only. Chicken Keri weighs 5lbs. Many thanks once again.
