New duck owner coop feedback

[B-Hawk]

Good Day my fellow Foul Owners! I am a brand new duck owner and would like some feedback on my first coop. My ducklings are a day shy of 3 weeks old now and have started to lose their down. I know that they will need to leave the brooder soon so I have created their pen (as best as I could) out of an old pool frame. I have absolutely no idea what kind of Ducks I have as the sign at the feed store stated "Assorted". But after reading some forums on here, I came to the conclusion that they will each need about 20 sqft of living room. (please correct me if I'm wrong) The frame is 10 feet in diameter so that's an area of 78.5 sq ft. For four ducks, I'm hoping this would be sufficient. They will spend their entire day out there 7 A.M. to 6 P.M. and then come inside for the night. (The pictures are just a test run to see how they reacted being outside)

With that being said, when did you all transfer your babies from the brooder to their final living space? Any and all feedback is welcomed! And if I stated any wrong information, please let me know. I can use all of the help that I can get! Cheers!

Ducks have about the same space needs as chickens, so 4 sq feet per duck in the coop and about 10 sq ft in the run.

Mine were exactly 3 weeks old when they stopped using any supplemental heat, so that's when they went out.

And the ducklings in their new digs.

All grown up.

This can wait until they are older if you want, but you could add a nesting area. It's nice when ducks lay their eggs where you want them to, and not places like in the mud next to the pool where they can get stepped on. Just a smaller sheltered area with soft bedding will do.
