Recently my chickens have gotten canker and I was wondering if I could use Metronidazole 500mg that my mother's doctor prescribed to her last year (it expires this year in october).
However, is there a difference between giving a chicken Metronidazole for humans and Metronidazole for fish(fishzole)? I know that I'll have to cut it up into smaller pieces since the pills are quite large.

As of right now I'm putt less than a tablespoon of Apple Cider Vinegar in their water.

As you can see it's really small because it's barely starting out. I also have another hen that might have it as well. (Sorry its fuzzy its hard to get them to stay still and zoom in at the same time)
 
On a general basis no antibiotics are approved for use in laying birds, due to the possibility of drug transmission through eggs.
Having said that, the majority of vets (both in Europe where I live and in the US from what I understand from friends who live there) are happy to prescribe them to backyard flocks, on the understanding that an egg withdrawal period of 2 - 3 weeks after the last dose is observed.
The risk is present, but the amounts transmitted are very small after the first week or ten days. It is obviously a personal choice, but one that many small flock owners choose to take in order to treat sick birds and keep them in good health.

When I have to medicate my whole flock I tend to calculate their entire weight (give or take), measure out the correct amount of medication, grind it up and mix it in with their daily mash. I know that they will all get some of it, and since it is in with their mash they will all eat a proportion of it - the bigger birds will eat more than the smaller ones. It may not be a very scientific method, but with 14 birds of varying weights it would be a nightmare to try and dose each one individually with something like an eighth of a tablet!

(You can also mix it in with a treat, but be careful as treats tend to get gobbled up by the more dominant birds, and the lower-ranking birds might miss out.)
 
The dose for Canker treatment is 50mg/kg according to http://www.poultrydvm.com/condition/canker

So, a 4lb bird would require 91mg/day. If you have 500mg tablets, you'd need to quarter them and then some. How much do your infected birds weigh?

Well I have 3 that are but some aren't as infected as the others:
1. An amerucana naked neck hybrid that looks like an amerucana probably weighs around 3 pounds. This one has two yellow thingys on boths sides of its mouth.
2. A silkie that weighed around 2 pounds last time I checked. This one has one small yellow lump forming on one side.
3. Another amerucana naked neck hybrid that looks like a naked neck probably weighs around 3 pounds. This one basically has like a dot of yellow forming on one side.

I've recently ordered thyme extract from amazon and I'm to see if I can use it to clean the stuff off with a swab before I start giving them medicine. I've also been putting Apple Cider vinegar in the water they all drink out of.

So, your 2lb silkie would need 45.5mg/day and your 3lb birds would each need 60.5mg/day.
You COULD crush up and fully dissolve 1/2 of a 500mg tablet in 2.5ml of filtered water. This would give you 100mg of metronidazole per 1ml of liquid. Then use a 1ml (1cc) oral syringe and draw the required dosage up to the indicated marks: the 45.5 mark for your silkie and the 60.5 mark for the Ameracaunas. Administer it to them orally, being careful to allow them time to swallow between drops in the beak so they don't aspirate.

You'll want to treat each affected bird. Canker is an infection and doesn't go away on it's own. Give the oral dosage for 5 days.
