I have a hen that I just noticed yesterday that has a swollen cheek. When opening her mouth, there was a cheezy substance in her cheek area, so I'm guessing it's canker. Thankfully, I have Fish Zole on hand and I started treating her yesterday. I've read to give her one 250mg tablet per day for 5 days. I've also read to give her one-half 250mg tablet twice per day. Which is the best treatment? Also, do the eggs need to be discarded?
