Hi everyone! I have a houdan hen that is about 5 months. She acts perfectly fine and eats and drinks like she always has. I have noticed the last couple of days when I hold her that she has an awful smell and it seems like it's coming from her nose or mouth. She does have a little bit of food around her nose which I've wondered how to get out, but I wouldn't think it would be that. I have no idea what it is. The other chickens don't smell. Any ideas???? Thank you!
