Congratulations!! Yes a suet feeder or a peanut feeder. I buy peanuts (no salt not in the shell) from the bird food store and they just love them. They also love the peanut butter suet I make. Just google a recipe.

If they're anything like my woodpeckers, definitely putting up a suet log will help. Mine will come and stuff their beaks full of suet to take back to the nest, and then when the young fledge, the parents bring them to the feeder. It's fun to watch.

Small update: I was out at dusk doing some last minute watering and debating on which pots to bring under the porch in case there was a light frost. I thought the little guy would've been asleep, but apparently my noises woke him up and he sat on the broken branch over his hole to watch me for a good 15 minutes, taking occasional flights over to some sycamores (he's flipping off pieces of bark, apparently for a before-bed snack).

However, when he finally flew back into his nest, I could hear the chatter of TWO birds. Look's like he's found his significant other. Now I can't wait for the eventual little feathery fuzzballs in awhile. I'll try to buy a suet feeder this weekend if I can remember.

Very cool to have woodpeckers nesting in your yard! Acorn Woodpeckers are actually colonial nesters, having sometimes up to 4 or 5 unmated birds that help raise the dominant pairs kids. So, you may see more birds show up...or not. In most woodpeckers, both sexes actually take part in excavating the nest cavity, although males usually share the brunt of the work.

Also, I was wrong on the ID. Definitely a downy woodpecker. I had the two crossed in my mind.
