Okay so I of course have Muscovies most people on this forum prob know that Lol just kidding but yeah anyway, I free range my ducks like they go out at 8:30 and go up at about 5-8 whenever I feel like they've had enough time or whenever they feel like going up. Anyway I was wondering about making their floor concrete since they're only in there over night essentially Should it be regular concrete or smooth concrete, they essentially have a huge dog kennel that I made into a coop by coating, rapping, shielding etc. all in chicken wire ( the top included of course) and so I don't have a permanent roof, I have boards that I put on top and then put a tarp on it ( again i only put that on when it's about to rain then take it off) But they poop a lot!!! ( Of course because they're ducks ) and I can't clean it off the dirt so would it be such a bad idea to just do concrete, and of course I would add bedding in the colder months and they would only be in there at night so what should I do??
