Hi everyone, I have a chicken whose nostrils are sort of cancave rather than convex -- the part of the beak that usually forms a "lump" over the actual holes. Ha! Sorry for the lack of technical/anatomical language! Instead of a lump hers are sort of sunken in, so the holes are just tiny slits. She seems to breathe normal and is thriving, in fact she's the largest of all my chickens. So it's not hindering her. I am just being a worried mommy about if this will become a problem in the future or if she were to become sick. She's about 4 months, a golden-laced wyandotte. I tried to take a picture but in order to show it, it has to be really close-up, which made the pictures too blurry. Thanks!
