Mendel was not the first to propose genetics however, he was the first to figure out that genes (he called them elements) came in pairs and that one member of each pair came from each parent. As a result of his realization regarding pairs of genes, Mendel determined what are called Mendel's laws of inheritance..
Chickens usually don't simply stop laying eggs when they get to a certain age, but they will lay fewer as they get older.That said, most laying breeds will lay more or less productively in backyard terms for five or seven years.hickens usually don't simply stop laying eggs when they get to a certain age, but they will lay fewer as they get older.
After your chicken lays an egg, the egg can either be taken away from the chicken and used for human consumption or it can be incubated until it fully develops into a healthy baby chick. It takes a chicken roughly 24 hours to form an egg inside her body and an additional 21 days after the egg is laid for it to hatch. Your chicken's egg starts forming when the yolk forms during ovulation inside the hen's ovary. At this point in development, the yolk is called an oocyte.
