SOME EXPECTED RESULTS

Some Expected Results. — ^Tests show that birds will react 

 favorably to lights in from seven to ten days immediately following 

 the application of the artificial illumination. During the winter 

 months, if properly handled, flocks may be expected to increase 

 their production from fifty to one hundred per cent over unlighted 

 flocks. If birds are handled properly under lights, there should be 

 no expectation of molt or decided check in production during 

 the lighted period or immediately following, or when the lights are 

 turned off in the Spring, providing in the latter case that the 

 lights are not turned off before April 1st, and further providing 

 the lights be reduced gradually. Birds under Ughts are surely 

 no more subject to roup, 

 colds, canker, or any 

 other diseases than are 

 unlighted birds. As a 

 matter of fact, the general 



results seem to point to ^HHH^^ - • *jSfe| pSflH '' 'J'''* 

 the fact that lighted 

 flocks are in better phys- 

 ical condition and more 

 resistant to disease. 

 Lighting is primarily a 

 feeding problem. By 

 lengthening the day, more 

 time is given the birds to 

 consume the food from 

 which they can manufac- 

 ture more eggs. It is not 

 a forcing of production 

 in any sense of the word. 

 Lights simply advance the season of heavy production from the 

 spring months, when the days are lengthening, to the natural 

 shorter daj's of the fall and winter. The lighted flock in December 

 and January resembles in every respect the heavy producing flock 

 in April, under natural conditions. One should never attempt the 

 use of lights unless he is willing to put every possible personal 

 effort into caring for his birds. The birds will not respond by 

 the use of light alone. First good birds properly graded, next the 

 lights regularly and properly operated, proper and careful feeding, 

 proper watering and lastly regularity in every practice, with the 

 greatest regularity in the hours of lighting.
