In the Brooder
I'll try to take a look, smell and get a photo of the inside of her beak today. She's a difficult one to catch. I actually found some acidified copper sulfate locally Thursday. I bought it and added to all the chicken's drinking water as a preventative if nothing else. As of yesterday (day 3.5), the growth that could be seen from the outside of the beak looks like it might be shrinking; at least in the corner of her beak. The first pic was taken about 24 hours after adding ACS to their waterers. The second pic was taken this morning.Can you get some photos of the the inside of the beak?
Canker would have a bad odor. Fowl Pox would be a possibility, but let's take a look.
Note: Just so you know, the patches of skin on her face where it's bald is due to a more dominant hen ripping at her beard.
