We will be breeding standard type birds for Type, temperament, vigor, egg production and finally color. One has to study type and cull, hopefully with some help from those who know. When it comes to temperament cull nasty birds, period. Vigor, cull those birds who do not display vigor. Period. For production, cull poor producers, however there must be a maximum safe yearly egg range? At what point if any would you omit a bird from your breeding program because it was too productive? In other words we know that max production results in health issues and a short productive life. What's the cutoff? Granted obviously it's not an absolute number, no one can give a number but experience show's there's a point where we're pushing the birds too hard. So what is an excellent egg production that is long term sustainable?
