I'd try the Acidified Copper first. What I usually do is get a 1 gallon water jug, put in 1/4 teaspoon of the Copper and fill with 1 gallon of water. I also add 2 teaspoons of Apple Cider Vinegar to make it palatable, the Copper is bitter and they can refuse to drink it. Mix up the jug each time before using and pour some into a quart waterer each day. This mix should last several days. Use this as sole drinking water for 10 days. You will need to use probiotics after treatment as the Copper will kill off all good bacteria and digestive yeasts from beak to vent.I smelled Eddie’s first and nothing was noticeable, Eddie doesn’t have any lesions in her mouth.
I then smelled Devs and there was really no bad odor. It might have been a little stronger than Eddie’s but it didn’t smell bad to me at all.
And I’m surprised to see that some of it has reduced in size overnight, it seems like it does that though. Where sometimes there’s a lot of it and other times they are small.
I already have both metronidazole and acidified copper sulfate ready.
Should I go ahead and give metronidazole just in case? Her mouth did not smell pungent though.
