Hatchability results indicated no significant differences between the fre- 

 quencies of gathering eggs from the nest. In fact, eggs that were collected 

 twice daily produced hatchability results equal to that produced from eggs 

 collected more frequently: this same pattern held true throughout the four 

 seasons. 



This work indicates that frequency of gathering eggs on the farm has no 

 effect on hatchability.

Intensity of Artificial Illumination and Its Effect upon Production in 

 Meat-Type New Hampshires. 



Many laying pens are poorly illuminated, the bulbs being of low voltage 

 and covered with dust. Some of the recommendations now state that a light 

 meter reading of at least two candle foot on the feeders is necessary and it 

 is doubtful whether the commonly used 40 or 60 watt bulbs will do this. 



An experiment was set up using January hatched New Hampshire pullets 

 using no lights. 50 watt bulb (1 watt per 4 square feet). 100 watt bulb (two 

 watts per four square feet), and 200 watt bulb (4 watts per four square feet). 

 Records were obtained for 296 days production July 10. 1951. to May 1, 1952.

There appeared to be a tendency for the 200 watt bulb pen to have re- 

 sulted in a somewhat higher rate of production, but that it did not appear 

 economical.
