Hi, I have a cross beak BO. I would say over the last month, her nostril area has visibly changed. At first, it was minor, one nostril looked like it was more shallow than the other. You could see beak shallowly under the opening. Last week, it looked like she had something sticking out of it, and it looked like a skin growth. She would jerk her head when I touched it. Today, I saw that the whole nostril is clogged off completely. There is no way she can breathe out if it. I know a picture would help, but my camera isn't charging properly and my phone took really out of focus pictures when I tried today. I am going to try tomorrow, but has anyone heard of this? Her cross beak is not severe like some I have seen. She is the hen in my avatar.
