DIPHTHERETIC ROUP.
(Diphtheria)
Cause.—Due to a specific germ. The disease is very contagious and is communicated by direct contact. Great care should be exercised, therefore, when showing or buying birds. Any new birds to be added to the flock should be kept in separate pens for a week or two to make sure they are in good condition.
Symptoms.—The first symptoms are similar to those of catarrh or cold. A clear, watery liquid escapes from the eyes and nostrils, the head is drawn in toward the body, the feathers appear rough, the breathing fast, the temperature rises from three to five degrees above normal. The bird walks about as if blind, sneezing, swallowing with difficulty, and showing signs of great weakness. If the mouth is open small white spots or elevations will be seen on the back of the tongue. There may be diarrhoea of a green or yellow color. As the disease progresses the discharge from the nose and eyes becomes thick and stringy, obstructing the air passages and gathering in large quantities between the eyelids. The mouth, throat and tongue are very much inflamed and swollen and in most cases it is impossible for the bird to make a sound. Recovery is doubtful after the disease has reached this stage.
Treatment.—Isolate the affected birds in some clean, warm, light, well ventilated quarters, excluding drafts. Dissolve thirty grains of Chlorate of Potash in one ounce of water and one ounce of Glycerine, and to the average sized fowl give one teaspoonful three or four times a day. To chicks give one-fourth the dose. When the scum loosens in the back part of the tongue, remove gently. Care should be taken so as to prevent bleeding. Feed soft, nourishing food.
DOUBLE-YOLK EGGS.
Eggs are frequently found with two yolks. This condition is produced by two ovary capsules bursting at about the same time and gaining entrance together into the oviduct where they are concealed in the same shell. Double-yolked eggs are larger than normal and may injure the oviduct when expelled. When hatched they produce twins or abnormal chicks.
DROPSY.
(Ascites)
Cause.—Generally due to irritating, indigestible food, causing inflammation of the membraneous lining of the intestinal cavity.
Symptoms.—The abdomen becomes enlarged, is tender to the touch and contains a watery fluid, the movement of which can be heard in most cases by pressure on the swollen parts. The bird appears stupid, the comb pale and the appetite poor.
