Reproduction stats — strain / breed comparator


Average production statistics over a season by breed
Values observed under our own rearing, egg-storage and incubation conditions — indicative for any other husbandry practice.
A breed includes all the varieties we select.
Some breeds are selected across several strains; here the data is grouped by breed.

Real data, not estimates

All the performances we publish come directly from our own farm and are calculated from our production results.
