Yup, depending on how the incubation went and other factors involved, some can go on for quite some time. Most of my hatches complete within 24 hours, however I like to think I have almost perfected my incubation and I don't typically hatch shipped eggs, which removes obstacles at hatch time...
Nope, 12-24 hours from last chick hatched. This ensures he has plenty of time to fluff up and dry well and gives the others time to follow along and hatch on their own. If a new one hatches, the waiting starts again.
Congrats on your hatch so far Mahonri! I always tell myself as long as chicks keep hatching, I'm not touching that bator. So you still have zippers..keep on waiting. I find I have best results this way. Best wishes and Happy New Year!
Hehe..don't go fussing with it now. lol I only remove the plug if the hatch finished (to allow for faster drying) or if it gets too wet during hatch (water droplets on the window). Otherwise, I don't touch it. Wishing you a wonderful hatch!
Mahonri, kathy is right in that there are a bunch of little holes all along the outside bottom edge of the 1588 hova. The single red plug you have you do not need to remove (at least I have never had to). The fan will circulate the air for you (which is where the 2nd hole is located on top)...
