My hen (Blue Laced Red Wyandotte) has been having trouble swallowing for the last two days, and yesterday I noticed clear mucus dripping out of her mouth after she took a drink of water. I opened up her mouth a few minutes ago and from pictures I've seen on the web, it definitely looks like Canker. She's about a year old now, and is a good layer. I don't want to lose her, but my hubby says "no" to bringing her to the vet, as we just can't afford it. And to be honest, no vets in our area deal with chickens. Can someone recommend some medication that I can pick up at a feed store?
