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.
Best Answer: It takes a chicken about 24-26 hours to form a complete egg. Some birds may take a bit longer. Layer-type chickens (leghorns) lay more eggs than brown-egg layers or other breeds because their clutch length is longer and/or their days between clutches is shorter.Chickens lay in clutches which means they lay around 5-12 eggs in a row (about every day) and then take a day or two off.ayer-type chickens (leghorns) lay more eggs than brown-egg layers or other breeds because their clutch length is longer and/or their days between clutches is shorter.
