OK so please be kind in your comments, but i have made so many mistakes trying to hatch some of my chickens eggs in an incubator. I have candled to much and I'll be straight with you I thought I done enough research and keep coming back here reading forms and finding i have made yet another mistake and miss understood some info. Well my first mistake was trying to build a home made incubator and it was going good for a few days then it went out and my eggs got cold like 66 degrees cold a week in to it. So i throw a lamp in the whole put a bulb in had my kids watch them while i rushed to TS and bought a foam incubator, without an egg turner. My second mistake was adding eggs daily so I have eggs I that are today at 21, 20, and day 19. they all are still alive i candled them last night and i have air pockets at the bottom like they should be and there is still good movement in the eggs. But no signs of piping. But i was turning eggs up until the night before last and I'm not sure my air pockets are large enough. Most of the eggs are tiny and all pictures i can find are on large eggs they look big enough to me but. I have been a straight fool through out this and I'm so scared that i am going to lose these little babies, I'm just soooooo mad with myself. I also didn't know to raise humidity to 65 to 70% in these last few days until the night before last. I now have it up but I also have both red plugs in the top trying to keep it up, but i read in one post that i should have both of them out, it has little wholes across the top on each side of the lid, but wasn't sure what to do. Do I live them in take them out, or take one out? I also read not to asst in hatching but have read where some say they have. I am at day 21 on a few and I know they can hatch late but if there is still no signs of piping tomorrow evening or Sunday (today is Friday 2/27/15) and I still see movement is there anything i can do to try to save the little guy? I am just beating myself up BIG TIME over being so stupid, i know better i should have researched every single detail first and now i have little lives at stake. Can anyone please help me and tell me what I need to do.
