They're using a 1 gallon chicken waterer, but they seem to know how to clean out their nares. They don't stick their bill strait in, they slide it through the water, that's one of reasons they make such a big mess lol. I check to make sure there's nothing stuck up their bills. They are really smart about a lot of things, except for jumping off of high things, they're literally parkour jumpers! I have to make sure non of them fall out when I open up their night time cage. They eat frogs!? Ewwww, poor little frogs lol. I'll share some pics of my duckies when I let them out, I've been waiting for it to warm up, it's kinda chilly out.
You are good at medical stuff for birds, or should I say, you know what to do for birds with health problems. I'll recommend you if I see any one else with a ducky in need 💖👏
I know usually if I see one running with a frog in it's bill it's too late the poor frog is dead. I do hide salamanders from them though. lol Even my chickens will catch a frog and eat it. mice too.
Got to watch the jumping they can really hurt their legs.. You sound like a great duck mum.
