I have an RCom 20 incubater. I have been incubating since last week. I candled this evening, and out of 9, only 3 look like they are developing. I do not have a hatcher. Is it possible to put more eggs in the incubater at this point? I know I need to raise humidity at a certain point, and that's my main concern. Any info is much apprwciated. Thank You!
