Chikapin Chestnuts

I planted two Chinkapins last fall. Due to poor planning I had to move them this spring and one died. I need a pollinator. Edible Landscaping doesn't have them this year. Does anyone know where I can buy one or even just buy some nuts to plant?

Will any other kind of chestnut pollinate it?

Thanks!

You can get plants or seed from Empire chestnut company in Ohio

Thanks!
