I can't believe I forgot about lockdown! I check the 'bator every morning and keep a log of temps/humidity in an Excel spreadsheet. This morning was Day 19. (I guess I must have missed yesterday.) I pulled out the auto-turner and added water (humidity had dropped to the 30's). One of the eggs was chirping very loud. Within 5 hours that chick had hatched (a white Silkie). (I love the sounds of chirping in the house.) I've got 34 more chicks waiting to hatch (Silkies, Seramas, and d'Uccles). I put 40 eggs in the 'bator and had to throw out 5 duds and ended up with 35 to go into lockdown. Gotta go get that brooder ready!
