I have a fourth Americuna doing this chirping (none of my other flock have done this.) They all have died, accept the current one which will probably expire soon. Hoping by reposting someone might have an idea.

Did they all eat anything new lately? I know it's an Ameraucana (bearded), but the bulge in the throat looks a little odd and she's throwing her head like she's trying to dislodge something. It could be what's referred to as Stridor (breathing), which can be caused by an obstruction or disease.

There are a number of respiratory diseases in chickens, such as infectious bronchitis, mycoplasma gallisepticum (MG,) coryza, ILT, and others. Those include viruses and bacterial infections.
