So I waited and no one else hatched so I cracked them open. I found the rest were fully developed but dead. So I checked on here and found out I should have had my humidity on 80%. I thought that might drown them but they were shrink-wrapped. So next time I am going to crank up the humidity to have a better hatch. I had 100% fertility and 15 out of 28 hatch for my first incubation with the incubator. This Spring, I had 9 silkie eggs under broodies and they hatched out 5 and 4 survived. So I am about the same as the broodies. I have 5 more duck eggs under a broodie in the coop. We will see what happens.
