Answer:

Mild cases can be cured by giving a tablespoonful of sweet oil and one or two tablespoonfuls of quite warm water, after which, knead the crop gently and force the contents out of the mouth, holding the bird head downward.

If the crop is hard and much distended and the above treatment fails to give relief, an operation is necessary to remove the obstruction.

Make an incision in the outer skin with a very sharp knife. It should be near the top and should be up and down, not more than two inches in length.

Force the crop to one side before making an incision in it, so that when the wounds are sewed up the one in the crop proper will not be opposite the one in the outer skin, but will be entirely covered by the skin.

After making the second incision remove the contents of the crop, after which cleanse it thoroughly with warm water in which has been placed a small quantity of any good antiseptic solution, four drops of carbolic acid to an ounce of water will answer the purpose.

Stitch the cuts with silk thread, being particular not to fasten the crop to the outer skin. The wounds should heal in five or six days.

Give no food at all for about twelve hours, and then begin feeding by giving milk for a day in small quantities at a time, then allowing soft foods, principally mashes, and in four or five days whole grain and the regular diet may be given.
