I'm putting together a treatment kit for my pigeons. I have flagyl planned for treating canker because it sold at a local store in 500mg tablets for fish. I plan to do flock treatment in water if canker presents. If the parents are getting treated from the water source, will the babies get treatment through the parent's milk? Or should I start looking for more sources of Metronidazole(Flagyl) in doses I can administer directly to the birds?
