It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich. Finding a place to safely place and hatch their eggs, and raise their young to the point of independence, is a challenge birds have solved in many clever ways. They use artistry, intricate design and complex engineering. The diversity of nest architecture has no equal in the animal kingdom.
1 The chicken breasts should be completely covered with the parchment.  Bake until the chicken is 165Â°F: Transfer the chicken to the oven until the chicken is completely opaque all the way through and registers 165Â°F on an instant-read thermometer. Start checking after 20 minutes; total cooking time is usually 30 to 40 minutes.
How long should a chicken be baked in the oven? The amount of time needed to bake a whole chicken depends on the temperature of the oven and the size of the chicken. For example, at 375 degrees Fahrenheit, a 3-pound chicken takes 1 to 1 1/4 hours to cook. At the same temperature, a 5-pound chicken takes up to 2 hours.
