This is my first time incubating!!! I have a dozen eggs in the bator! Really hoping I have some hatch as my 3 year old daughter is pretty excited to have chicks!! My humidity is reading 40%.. I just bought a hygrometer from the store to make sure it's accurate.. I'm worried there isn't enough humidity?? It's so hard to know!!! Also I added 1 egg a day later then the rest.. Will that be ok for lockdown??
