I have one Silkie rooster who has always had a crooked beak. It's not too terribly bad, and he can still eat, drink, etc, but could a crooked beak be bad for a chicken? Could it create respiratory problems? Because he has also had this sort of 'sneeze' thing since he was a little baby. He's a healthy bird though, other than that. I really don't want to cull him just because of a sneeze. He's almost a year old now and lives with 2 other hens who have never developed this 'sneeze' that he has. Should I be concerned?
