The transfer from the rearing farm to the laying facilities is a major stress, accompanied by changes in environment (temperature, humidity…) and equipment. It should be carried out as fast as possible, ideally being completed within a day. Then, between transfer and the peak of production, a rapid increase in feed intake is necessary since the bird has to cover: - its growth till adult bod...
In case of open house it is difficult to encourage additional feed consumption. Because there is no way that temparature and rel humidity can be controled. However, night feeding is possible which do not give significant result. In my opinion, birds should be transfered by 14th wk but in no case later then 15 wks.
In open sided houses varying light intensity becomes a problem. In such cases birds are exposed to three condition, Natural light, Artificial light and Darkness. Birds appear restless in this case.
