I don't, it's very hard to keep her beak open long enough to take picture with my terrible camera. But I will try.
I have removed the canker twice during this process. Pieces the size of a pea. The last time it bled and left her beak swollen so I'm hesitant to remove it again and feel like I don't have to because it doesn't seem to grow. Her breathing is also quite fine, no noise or visible difficulties. It's just that she cannot swallow things on her own. Even when feeding her liquid food with a syringe she has troubles swallowing.
She has been separated from the flock, but she doesn't eat/drink on her own anyway so there is no chance of her spreading it like that.
Other than that she is active and still tries to eat when I offer her snacks, she just doesn't manage to get it down.
Here in the area (portugal countryside) there aren't any avian vets. We have visited many when we had a dying chicken but they all looked at us like we were crazy and told us it's cheaper to just buy a new one
