[levitc1990]

i have hit day 20 with my coturnix quail i have one more almost out and i think that will be it i got 8 out of the eggs i bought 18, i know not so good but i learned alot in the process. it was my first time incubating, the ones that have hatched are doing wonderful. my questions are i had a heck of a time keeping that humidity up for them, and can anyone give me any helpful information about incubating coturnix i have done alot of research but want people that have actually done it alot.
