CAUSE.—Exposure; the bird chills, causing contraction of the blood vessels near the surface of the body, thereby forcing a large quantity of blood to the internal organs; the small blood vessels in the lungs become distended with blood and rupture. SYMPTOMS.—Rapid and difficult breathing; the bird appears stupid and sleepy and does not care to move about; appetite poor, wings drooping, plumage ruffled, a thick mucus, colored with blood, escapes from the mouth, comb and wattles show a dark-red color from lack of oxygen in the blood. This disease is of very short duration, the bird dying within a few hours. It is very common among young chicks and turkeys that are permitted to run out in the early spring rains. TREATMENT.—Medical treatment is of no value, as the disease progresses so rapidly that the bird dies shortly after the first symptoms appear. Sanitary surroundings, good light, pure air and exercise are essential. Do not allow the birds to stand out in the cold or rains, especially during the molting season. Keep your poultry strong and vigorous by feeding clean, nourishing food and give them pure water to drink. CONSTIPATION. (_Intestinal Obstruction_) CAUSE.—Irritation of the membranes lining the intestines, caused by dry feed, glass or gravel; may also be due to parasitic worms. Obstruction may occur in any part of the intestines although the external opening is the part most frequently affected. SYMPTOMS.—Bird appears dull and stupid, walks with difficulty and attempts frequently to expel the obstructing material. The appetite is poor and the feathers rough. By examination and manipulation the obstruction may be located. Dried masses of excrement by adhering to the feathers sometimes block the outer opening of the intestines. TREATMENT.—Remove the waste matter clinging to the feathers with warm water or by clipping the feathers off. If the Cloaca is obstructed, give injections of Sweet Oil or Olive Oil with a small bulb syringe. Also give one to two grains of Calomel and feed clean food and soft mashes containing Pulv. Gentian Root, one grain to each fowl twice daily. This stimulates the worm-like movement of the bowels and assists in expelling their contents. CROP IMPACTION. (_Obstruction, Paralysis, Inflammation, Catarrh_) CAUSE.—Errors in feeding; birds that are not fed regularly are predisposed to any of the above conditions; may also be due to swallowing large pieces of bone, thread, nails, pins, glass, gravel, etc. SYMPTOMS.—Loss of appetite, frequent attempts to swallow, crop greatly distended and hard on pressure; eventually the food decomposes and a liquid may escape from the mouth and nose. The bird appears dull, stupid and sleepy, comb pale, feathers rough, beak open, owing to pressure on the windpipe. If caused by swallowing sharp objects, they may penetrate the crop and skin, causing a gangrenous condition. Grain in the crop will sometimes send out sprouts of considerable lengths.
