Considering the effort it takes, producing an egg a day could easily be called an olympic discipline for all hens around the globe. A neverending excercice which, without the right genetic tools, even seems close to impossible to start with. Therefore it is wise not to count on genetics alone, but to also give your hens that little push in the back by means of carefully selected supplementary feeds giving you that little edge that makes the difference between "good" and "outstanding"....
Mercordi might just help you with that
