I set eggs 23 days ago. I put 7 into my Brinsea 4 have hatched. No problem there. I put 30 into my Hova Bato, only one has hatched. I checked the eggs around the 14th day and all these eggs seemed viable. The temp is running at about 99-100, humidity is about 58%. I filled it with water and put a sponge in before lockdown. I have to remove the one living chick, should I check the eggs when I move her to the brooder box? Any suggestions are welcomed. How long do you keep eggs before throwing them out?
