Quote: My birds are not genetically weak and not the result of too much inbreeding. The small size is the result of selective breeding. As for "year old birds", I disagree believing it more important to look to the health of the hens and the quality of the eggs to be hatched. My flock is healthy, the overall hatch rate is good, and the vast majority of chicks that have hatched grow into healthy adults. I will continue to let my young pullets brood when they decide it is time to do so.
