In chickens exposure and neglect are alleged causes. Foul coops and the
contrast between the warm building and cold outer air are justly blamed.
Ruffled feathers, drooping head, dark colored comb and wattles, trailing
wings, a disposition to gape, panting and cough are noticed. Under the
wings and over the back crepitations and dulness may be detected. The
patient may take a teaspoonful of castor oil, and saltpetre or iodide of
potassium may be given in the drinking water. In careful doses the other
remedial measures may be attempted.
