Incubation & Hatching
101.5 degrees F. in a still-air incubator
99.5 degrees F. in a forced air incubator
Chickens: Relative humidity should be 50 to 55%. Some say to raise the humidity the last three days to 58%. Guineas are the same.
Waterfowl: Relative humidity for goose and duck eggs is 63%, raise the humidity the last three days to 70%.
I've been asked several
times about homemade incubators. The only plans I've found so far in a book are in Raising Poultry the Modern Way, by Leonard Mercia, ISBN 0-88266-058-6.

Large and small incubators are available from many of the suppliers I have listed. They are also available from many of the hatcheries, but usually at higher cost.

Note: If a chick is having trouble getting out of the egg and you want to help it, be aware that most in this condition are already weak and usually die, which can be more emotionally traumatic for you then if you didn't help.
