Glad my Corid info helped! Many don't know this, but I had to do *lots* of research and math on amprolium before I felt comfortable going public with the dosing info. Many people couldn't wrap their heads around the fact that the 1/2 teaspoon powder per gallon dose was wrong, many still can't, lol. The 1/2 teaspoon Corid misinformation is what prompted me to dust off the math skills part of my brain and start calculating proper doses, and to start weighing powders.
Not sure why Corid isn't labeled for poultry, 'cause AmproMed P and Amprol are, and they do have instructions for poultry.
Did you know that most powdered poultry medications weigh 2.5 to 3.3 grams per teaspoon? Silva's, the feed store by me, will sell me powdered medication at cost if the expiration date is near, or they will give me the ones that have expired. So far I've been able to get my hands on Durcmycin 10, Oxytetracycline (10 gram per bag), Corid, LinxMed-SP, and a friend has weighed SulfaMed-G.
As for vets, give them the benefit of the doubt, 'cause they have great resources to draw from, so most dosing info from them will be accurate. If the amount seems way off, talk to them about it and ask why it's different than what you think it should be.

Thx for your input. I didn't mean to put down my vet -- it's just doctors are always in such a rush they gloss over stuff that they assume you already know -- just because I have 4 hens doesn't mean I'm an expert about what's medically needed for them. By the same token he's learned stuff from me too. He wanted me to shove syringe meds down my hens' throats and I had to show him how easy it was to have them drink the meds on their own either from a dropper or out of the palm of the hand. Said he never saw such tame hens! It's not easy to find a vet good with birds that doesn't cost an arm-and-a-leg and I'm lucky he's only 10 minutes away! Oxytetracycline used to be easy to pickup in pet stores decades ago. My feed supply store only caries the minimal basics and sometimes I have to special order just simple vitamin supplements or wormers like Rooster Booster which I would think should be staples on the shelf considering the huge chick and adult sales they do.
