In handling affected birds, therefore, care shoidd be exercised to prevent infec- tion of cuts or scratches. Treatment. â Diseased birds should not be intro- duced into a flock. If the disease has been acciden- tally introduced the af- fected birds should be isolated as soon as possi- ble. The flocks should be watched in order to dis- cover and isolate any new cases that appear. In early stages the dis- ease yields readily to treatment. Ziirn considers treatment economically advisable only before the feathered parts of the body are attacked. The disease may sometimes be cured at a later stage. The value of the affected bird must determine whether or not it is worth treating. As much of the crust as possible should be removed. This.
