I decided to only do four hatches this year. Hatch A started with 7 fertile eggs. Three made it to externally pipped but then died. I couldn't figure it out but I suspected the hatcher...separate from the incubator. Two others did make it and are growing well. Hatch B started with 7 eggs also and after one reached externally pipped and then died, I threw the hatcher away. I put the remaining eggs in the bottom of the cabinet incubator and three hatched. I'm currently waiting on Hatch C with 6 eggs still going and Hatch D will be next weekend with 10 eggs still going. My first two hatches gave me three blue goslings and two lavender ones. Hoping for a few more babies!
