not sure what ya mean but if for chicks thats a bit early~? not sure if you mean hatching over two days~ if so then well I personally dont think thats really off the time table~even my hens can have their hatch over 24 hours some late chicks closer to 48 hr mark of the first chick out. not all together at once. maybe going way over 24-48 hours would be a slow hatch? sure other folks give you more detail.
