I have only done one hatch before(if you can call it that). Last year, after a coyote attack that killed all but one of my 10-chicken flock, my survivor chicken laid an egg. I ran out and bought an incubator and stuck it in there.... against all odds, it hatched. I have since acquired more chickens to keep survivor bird company. On the 10th of March I decided it was time to try hatching again - it really was fun the first time, even with only one (I mail-ordered day old chicks (4 of them) that arrived the day after she hatched so she wouldn't be alone). Anyway, I set 12 eggs on March 10th and candled them once on day 15... they are brown and hard to see through, but I think most of them are viable (I don't have any stinkers). Today is day 17 and my turner is making a grinding noise and it appears it is no longer turning. Am I safe to go ahead and take the turner out and lay the eggs flat for hatching? Or should I be hand turning them?
