I am on day 22 of my incubation, no chicks....when I locked I candled them, they were all grown inside egg....I just checked a few, no movement...large air sac...what did I do wrong? I don't know the humidity...I have both trays full of water, the temp is at 102*, I read that that was the optimal temperature for a still air incubator. Did I kill them all? Should I wait another day or so? I just candled 4 of them to check..no movement, no cheeping...nothing....I have 18 chicks in there!
