My mom claims that the 3 week old ducks shouldn't be allowed in water outside. My dad say it's fine. It's about 68 degrees out (Texas) and the water wasn't really even cold but not warm either. What temperatures are okay for ducklings (1 mallard, 1 black swedish, 1 white pekin)? They seemed fine in it, they love it. And I'm makin' sure they dry off okay.
