Don't worry too much, each batch you set are different. Some start the hatch train sooner and some start later.. drives me crazy! I did 6 quail hatches (about 60 eggs each) back to back and each one was different. From the one befor.Still nothing, I set my eggs at roughly 3 pm pm on Saturday April 6. Technically it's day 19 but my "hatchabatch" app says it's day 20. Haven't heard any little voices yet and starting to worry!this hatch feels like it's more rough and stressful than my first "I don't know what I'm doing" hatch
