I have two Orpington hens that lay fertilized eggs. After two weeks, day-before-yesterday I finished gathering and putting two dozen eggs into the incubator and starting it. During that time, the last two days I had to take an egg out from under a freshly started broody hen. Starting today, I will let her keep the eggs she lays, and I will put the eggs from the other hen under her.
QUESTION: For how many days will it be safe to put/add eggs under her, i.e., when will she actually start incubating the eggs all together so that they will all hatch within a day or two of each other?
