This disease is normally found in chickens more than four months old. They pick it up in the first
few weeks of their life, or from the mother which, if affected, passes leucosis through the egg. The
tumors develop slowly; birds become sickly, pale and thin, and often have an enlarged abdomen.
There is no known effective treatment for leucosis, nor are there any vaccines available. Affected
birds should be culled from the flock.
