Good Morning Everyone I am new to this site and have a few questions. I recently bought a hova-bator incubator and egg turner. I have read several different things about the vent plugs one thread says to leave it in for the first 10 days. One says to have at least one vent plug removed during the incubation process. Just wanted to get a little more information prior to setting eggs. the incubator is a fan type model. Also I was wondering what is expected for a hatch rate? I understand that there are several variables in this.
