I got my Ameraucana hen when she was 1 year old back in October and ever since I have had her I noticed she breathes weird. Often she has her mouth open. I got her with two Barred rocks of the same age and have since added two more chickens to the flock. None of the other hens breathe like that but they are different breeds... is it an Ameraucana thing? Anyone know what the deal is or if I should be concerned? It's sort of a heavy breathing that gets worse when shes scared or excited. She doesn't seem sick in any other way. She eats, drinks and has normal poo... Maybe she is just a mouth-breather but she hasn't laid one egg since we got her. She also has this loud bark like cluck and I never hear her egg song.
