Whether deathlayers, silkies, seramas, fayoumis or Jersey giants - they are all the same species. Gallus gallus domesticus. Therefor they all require the same temperature -99.5.
However, humidity needed will vary by breed and strain due to variations in porosity of egg shells. If you haven't incubated a breed's/strain's eggs before, rather than shoot for a specific humidity, the best bet is to weigh eggs rather than shooting for a specific RH%.
I usually weigh before setting and again at 5-7 day intervals. You are shooting for 12% weight loss for all avian species from fresh to pipping at which time you need to dramatically increase humidity.
Make a graph so you can plot ideal daily weight loss. Whenever the weights you measure move outside that line, adjust humidity accordingly.
