when a rooster breeds with a hen, how long are her eggs considered fertilized??? Just the next egg she lays? Fertile all week? Just wondering in case I decide to raise a few chicks. And does a hen go broody randomly or does this increase when she lays fertilized eggs??
I have never had much luck hatching eggs if the hen and rooster have been apart for more than 5 days. This was while single mating one rooster to several hens and endeavoring to ascertain what hen laid which egg. In my experience any longer than this means that you have a Romeo Rooster climbing up to Juliet the hen's window at night.
To show you how variable this can be, once a tom and hen turkey breeds just one time, the hen turkey can lay a whole clutch of fertile eggs. But turkeys are not chickens, and chickens are not turkeys.
