Ducklings and Goslings do not take heat well, so be sure not to overheat them. They like a temperature of 90-92 degrees for the first 3 days, then 85-90 degrees for days 4 to 7. Thereafter, drop the temperature by approximately 5 degrees per week until they are fully feathered.
In his home based machine shop, McCoy invented an automatic lubricator cup for oiling steam engines. This was his first patent, âImprovement in Lubricators for Steam-Enginesâ granted on July 23, 1872. It is believed this was the origin of the term âthe Real McCoyâ because engineers would ask if it was âthe real McCoy, when buying lubricator cups for trains. Elijah McCoy held some 60 patents by the time of his death in 1929.
