I'm planning on buying a Brinsea Maxi II advance this week and have found a couple of local breeders to buy eggs from (2 different breeders, about an hour away). The breeds I was going to start with are silkies, Polish, and Americaunas. I've never hatched eggs before, and the silkies and Easter Eggers I had last season were wiped out by a predator before they laid eggs, so I'm not sure how their eggs compare. Can I put all three breeds of eggs in the incubator together? I know there is an insert for smaller eggs that could be used, but would the Americauna eggs fit with that? Or would the silkie eggs fit in the regular holders for that matter? I don't want to buy all three and end up not being able to use half the eggs because of size.
