I don't think it is ready. I see a green stripe and the rind isn't very "orange". Most butternut squash are mature in August or September in this part of the country and later up North.

They look immature to me. They are still edible. If the flesh is soft enough for easy slicing you can use them like summer squash.

When you cut them open, look at the seed development and you'll see how far along they are.

They are hard already and we ate one already like my Grandmother fixes them. It was fine, baked with butter, salt and pepper. I do plan to wait on the rest though.

So I am clear, I should wait until there is no green line and they are dark orange?
