Silkies should probably use normally recommended humidity. If you experience shrink wrap issues, use that result as your guide.i did not know there were preferred humidities for various breeds of chickens. What about Silkies? Of the not so many chicks I've incubated, the Silkies have tended to have the greatest problem with shrink wrapping, so I wonder. Is there a book or publication that discusses incubation in such detail? Or maybe a thread on BYC? Thanks.
Extremely dark eggs or thicker shells can go with lower humidity.
I find that weighing eggs is important when hatching a variety of eggs or when beginning to hatch with a breed.
I actually need to cover up some of the air holes on the bottom. I can't get the temp to rise out of the very low 90's.
It's basically already spring here. It's been in the 70's for the past 2 days. Today it's cold, but tomorrow it's going up again.
Rather than closing holes, I recommend enclosing the incubator in a space surrounded by cardboard or boxes or anything that will create a mini room. Not to restrict air flow just to make a space that will limit heat loss. You can also put some towels on 2 sides to hold heat in. The growing embryos need oxygen.
