Math is not my strong point. Hoping someone can double check to make sure I am doing the days correctly. I have button quail eggs in the incubator. Lock down for button quail is at 13 days and they can be expected to hatch around day 16. They were placed in the incubator today (April 14th) at 11:40 am. Lock down should be April 27th at 11:40 am, right? Thanks!
