I have an 18 week old Lav Ameraucana that just this evening began making a funny sound... As if she is whining while she breaths... As if she were wheezing, but it sound more like a quiet chicken noise or whine and less of a wheezing sound like breathing. Every so often she then 'barks' for lack of a better term/description. Hard to explain... Any ideas? Haven't seen poop yet, am trying...
