I put the none digital incubator to 99.5 degrees, that's what the owners manual said for chicken eggs. I put the eggs in the egg turner for 18 days, then, took the egg turner out, and set the eggs in there for 3 more days, for a total of 21 days. Also, I had to keep some water in the bottom of the incubator so the eggs didn't dehydrate. Well, the chicks didn't hatch till about 24 days. Out of 12 eggs, I had 1 chick with a crooked leg hatch, and he/she died at about 2 1/2 months old. So I tried another batch, this time 24 eggs, and after 24 days again, I had one hatch, then die, and one almost make it out of the egg, then die. Then on the Internet, I found the temperature should be 101.5 degrees, and I have to keep track of the humidity level. It's been almost a whole year since I've tried at hatching, and if anyone has any tips I would be so very grateful!
