Occurring without gain or loss of heat. When a gas is compressed under adiabatic conditions, its pressure increases and its temperature rises without the gain or loss of any heat. Conversely, when a gas expands under adiabatic conditions, its pressure and temperature both decrease without the gain or loss of heat. The adiabatic cooling of air as it rises in the atmosphere is the main cause of cloud formation.
Turkeys lay from early spring to early summer, a span of about 4 months. During that time the turkey will lay 12-18 eggs and then sit on them. If you collect their eggs they will continue to lay, eventually producing an average of 1 egg every 2 days for a possible total of 80-100 eggs.
Most producers like flocks to begin laying at around 20 weeks of age. A flock of hens will lay efficiently for 60-65 weeks. White egg birds will lay 260-285 eggs a year and eat 3 pounds of feed for every dozen eggs they produce. Brown egg layers will lay 240-280 eggs a year and eat 3.5 pounds of feed for every dozen eggs they lay. Once the hens lay for 60-65 weeks, they are rested or molted. This will force all the hens to stop laying at the same time and allow them rebuild calcium stores and restore body condition.
