Are our Pekins both drakes? (Video)

[KTmomma]

While we were at TSC to adopt our second batch of chicks this summer, my daughter fell in love with a pair of fuzzy yellow ducks. BOY did they grow FAST!! (It was three months ago yesterday, so they're 13 weeks and weigh about 10 lbs each.)
We suspect they're both drakes based on videos we've watched of Pekin ducks quacksing, but I can't really discern between what I hear on YouTube and what I hear from our feather babies (and we are still so new to ducks...)
They're super sweet with each other and the chicks they were raised with, and we'll keep them either way, but would appreciate your thoughts on the pair.
I couldn't upload a video here on BYC, so I put it on YouTube: Are We Drakes?

They are cute! If both make that sound, you are correct, both are boys.

Thanks! We were hoping for girls -- at least one -- but they'll still have a home here.

yup drakes.
do they live with the chickens?
If they try to mate with them they will injure/kill your hens.
drakes have penises (and roosters do not because chicken hens are not built to accommodate them)

Separate from your hens neither will mind.
Your boys are beautiful.
