(a) food
(b) warmth
(c) light
(d) amount of water.
The correct answer is option (c) light.
Light is found to have a significant effect on egg laying by hens in the hen houses or poultry. Photoperiod is the length of the time within a day to which the hens are exposed to sunlight or artificial source of light. Egg production is reduced if the light intensity and duration is reduced. A peak production of hens is observed with the photoperiod is lengthened or a longer photoperiod.
Natural day light exposure to hens results in the production of not more than 40 eggs. Whereas, a prolonged day light of 12- 14 hours by indoor lighting increases the number of eggs layed to around 60 eggs. Thus, the stimulus for egg laying is the light.
Thus, In a hen house, if the length of daylight is prolonged by using indoor lighting, the stimulus for egg laying is light.
