I have 4 silkiehens and a silkie roo that are laying fertiziled eggs. My neighbor wants to raise a couple of silkies to add to her flock. I am willing to give her some eggs to hatch, but not sure what temperature to hold them at for a couple of days before she adds them to her incubator. I am getting 1-3 eggs per day that are likely fertile. 3 of the hens are are about 5 months old. The other is about 3 years old and a prolific egg layer (almost one per day). Any advice on pretreating hatching eggs will be appreciated.
