There are 2 topics in this thread; 1 regards the incubator's vent plugs and their usage, and the second speaks up about my quails' eggs (blue-scaled quail) not hatching and also how long it really takes for new-world quails to hatch. INCUBATOR'S PLUGS: Now I'm going to need some help here. There are 2 red, plastic plugs that seal each vent on top of the incubator. What do I use them for? Do I unplug them and leave it like that? Or do I leave them on? Some will say that those plugs help to regulate humidity, some say they regulate oxygen intake, and some assume both. Some might say that the plugs don't matter, while I've heard of those say that they're very important and must remain unplugged and/or sealed shut during hatching, or during the entire incubation process (including hatching). QUAILS' EGGS: I'm using a Little Giant incubator with 13 blue-scaled quail eggs. The date I posted this (Jul 15) marks day 27 of incubation. I put the eggs in on June 18. But, the eggs are still not hatching. I've heard of one whose bobwhite quail's eggs took 28 days to hatch. How long did it take for your quail (New-world quail) eggs to hatch? Please help!
