Hi...i have some eggs from cjexotic and they are on day 21 tomorrow but a few pipped last night and this morning i have a splash and then while i was looking at the chick another one cracked out and its a nice splash too....is it safe to leave them in the incubator until tomorrow night as my nankins all popped out like popcorn and then i just got them out....i also wanted to add that i have a brinsea 20 and to keep the humidity up i ran an IV tubing thru the bottom vent holes into the water channels where i place some sponges then on lock down i got what is a palette sponge very thin for keeping paints wet for up to 3 days i cut a piece off and put it on the bottom of the incubator under the hatching tray and then there is a larger surface for the water to create moisture....i have been able to keep my humidity up in the 65-70 range with no problem..you can buy them at Cheap Joes art supply or Dick Blicks they are called Sta Wet palette sponges...its hard to stay away from that incubator with all the hatching going on
