For the first 18 days the humidity needs to be between 30-45%rH and then increased to about 60%rH for days 18-21. Temperature should be 37.5*C
The eggs need to be rested for 24 hours, pointy end down when you receive them before you set them.
Have you really though this through properly? Hatching at this time of year is time consuming and electricity consuming.
If you set them tomorrow (for instance) they would be due to hatch on approximately 13 Oct.
At 6 weeks old, when they would normally be going outside, it will be 24 Nov. Chicks do not cope with cold/wet/wind as well as adult hens, so you will probably need to keep them inside for longer.
When they are inside (including the 6 weeks when they are very small and unfeathered), they will need constant heat, and they will also need supplemented lighting as they days aren't very long now to ensure they eat enough to grow properly. Winter hatched chicks are often smaller than spring hatched chicks due to this very reason.
You needn't wait that much longer if you're eager to start. If you set eggs in at the beginning of Feb, they're ready to go out by end of March, with a little care and attention; and hatching early in the year is always easier, as the days are getting longer, and the weather getting warmer.
One other thing to consider... the mating "season" is well and truely over, so the fertility of the eggs cannot be guaranteed at this time of year, especially if the breeders keep large pens (having said that most breeders I know break up their breeding pens in about Jun, which is just about the "end" of the hatching season).
Please think of the welfare of the future chicks before you rush in, especially if it is your first time hatching
