so tomorrow is 7 days after I put in the duck eggs so I'll be putting in the chicken eggs. Should I candle the duck eggs to see if they are developing? This is my first time using an incubator. Before I always let the mamas do the work. But it can be hard on them and I like keeping their feathered butts free to keep my garden picked clean of pests. Also, I have more chicken eggs than I need, and they are all sooo lovely and I am having a hard time picking. I think I'll put in a variety of sizes and colors, though I won't be putting in the long narrow ones. Ok check list Humidity well not sure of the percentage I filled in the pan the machine told my to fill in and then before lock down i'm suppose to fill in the second fan. It's one of those simple , hand holding, does-all-the-work for you, incubators. Temperature,100 degrees fan, check egg turner, working eggs... well lots of them Excitement... through the roof! Eeeeee! BTW what is the usual hatching rate in an incubator? anyone know?
