My husband bought me a Brinsea octagon 20 advance incubator for Christmas this year and I was so excited to collect the eggs and hatch them. I had 18 eggs to incubate (yes I do have a rooster) however they all had Brown shells so it was never really easy to see clearly when candling. There appeared to be some changes but I started to lose heart when they entered the 3rd week and had not started filling the shell. Last night (day 23) I prepared to do a little autopsy on them. All 18 of them appeared to be around day 3 or 4. Could see the red blood from where the eye would be and the yolks were liquid, not formed like an egg you would crack to eat. There was no odor of any kind. The readout on the control panel showed humidity was 40 to 50 and the temp was set at 99.3 -99.6 throughout the entire incubation period. Any ideas on what might have gone wrong?
