I just had my first quail hatch this weekend. For the most part it went well but I was using a homemade incubator and had some not develop completely. I was hoping someone could tell me what might have went wrong so I can fix it for next time. Half of the eggs that hatched were on day 17, the other half the morning of day 18. I set them around 10pm so I think my temp was good. I set 28, 10 hatched, 3 were mostly developed, 5 were a 1/4" blob with eye, and the rest looked either infertile or had been too damaged during shipping to start development. The incubator is heated by 2 light bulbs and has a fan connected so it turns on and off with the lights to circulate the heat. For temp I used a Spot Check with a fake silicone "egg" so I could monitor the internal egg temp. Temp held between 99.4-100.0. 90% of the time it was right at 99.5-99.6. The eggs were shipped so I left them big end up for the first 5 days then started rotating 3 times a day. Humidity was around 40-50% untill day 14 when I stopped rotating and turned the humidity up to 60-65%. I used two cheap humidity gauges so I just took thier average to figure around where I was. They were 5-8% apart. When I locked down I noticed some of the insulation had expanded and partily blocked my air vents, so I opened them back up and created another larger vent. So there may have been a lack of oxygen for the first 14 days. First, the 10 fuzzballs that made it. 5 tuxedo, 4 common and 1 texas A&M (I bought a grab bag of eggs for some variety) Sorry for the dark pics, my camera won't flash with the red heat light for some reason : Don't scroll down past the first two pictures if you don't wanna see poor dead chickies 4-5 looked like this. About a 1/4 blob with an eye. Out of these three, two both had exposed brain so the skull wasn't fully developed, they appear to have quit within a day of eachother. The third looks complete, there was even a little poop in the egg with him and the yolk is still there a little bit. Thanks for any advice.
