Fever
The most decided species of fever to which fowls are subject occurs at the period of hatching, when the animal heat is often so increased as to be perceptible to the touch. A state of fever may also be observed when they are about to lay. This is, generally, of small consequence, when the birds are otherwise healthy; but it is of moment, if any other disorder is present, since, in such case, the original malady will be aggravated. Fighting also frequently occasions fever, which sometimes proves fatal.
The symptoms are an increased circulation of the blood; excessive heat; and restlessness.
Treatment. Light food and change of air; and, if necessary, aperient medicine, such as castor oil, with a little burned butter.
