Are D’Uccles heat hardy

[Riverbend Farms]

I am planning on getting A couple D’uccle hens/pullets, and I wanted to know if they are heat hardy (talking about an average of 93 degrees to 107 at highs), like I get they will need to be cooled down, but can they survive 90s to 100 with little help?

Many years ago my neighbor in Texas raised them. She didn't seem to have any issues with them and the heat.
They sure are cute little things
