A.The egg came first: DNA in the fertilised egg of a chicken-like bird mutated & that egg developed into an embryo that emerged as the first true chicken.
A.For the perfect soft-boiled egg with a runny yolk, boil for 3 minutes. 3.5 minutes gives a set yolk, 4 minutes a hard yolk, and 7 minutes is hard-boiled.
Q.How many eggs does an average hen lay.
A.Hens typically lay 5 eggs a week, but it will depend on the age of the bird and the breed of chicken. The average hen lays about 260 eggs a year.
Q.Is there any chance a supermarket egg could hatch
A.Eggs bought from most supermarkets are not fertilised and so won't hatch into chicks. They are laid by chickens without the help of a cockerel.
