THere is a possibility that it would improve the survival rate of DOC. But it will have a negative effect in the other stages.
Yup, it will drive the price up. Although, currently from as high as 97 pesos farm gate price , i think the farm gate now of broiler is around 60-70 pesos.
Also, a commercial raiser told me that some rumors are spreading that hatcheries are creating a pseudo void in the supply chain by sacrificing some DOC so prices will be at a high level. Just a rumor....
