For those of you who want to heat a grow room though, I suggest you look at this heater: Lasko 755320 Ceramic Tower Heater with Digital Display and Remote Control. The slimline tower design means that its space saving and the large digital display at the top mean you can easily see and set the room temps.
Peacock eggs will hatch within 28 to 30 days of beginning the incubation process. On day 26, move the eggs into the hatching space and do not touch or turn at all. The hatching area is a simple basket where the chicks can safely move around as they hatch. As the chicks hatch, move them into a safe space for rearing.
You may have a peacock egg incubator with a hatching tray or area, or you may choose to use a separate peacock egg hatcher. Either one can give you great results if you carefully monitor your humidity during this delicate time. You will want to stop turning your eggs at day 26 and relocate them to your hatching area. This allows them to properly orient themselves for hatching. They should begin to hatch within 2-3 days. You can leave the temperature the same as for incubating (99-100 degrees F), but you will want to increase the humidity.
