Set 5 eggs in my homemade incubator 2 weeks ago. Lost power on Monday while we were out. When I got home late, the eggs were cold. Temp in Bator dropped to 50 degrees. Power was off since early morning. Bummer. First time incubating. Cracked open one & little chickie was cold too. So sad. Power back on now. Gonna set some more & try again.
