And I read up.
I hope your duck is doing better by now.
Please tell me where you found that Vitamin B complex for pidgeons.
I have never found anything like that here in the Netherlands. The closest I came with people recommending me uuh.. Nyancin/breweryeast?? When translated it was 'bakkersgist'. That stuff you put in dough to make it rise; That sounds bad in a ducks stomach so I guess there is a translation mistake; allthough I have found it for humans in one of those hip gym-people vitamin-bulk store. But, that is for humans.
I manage to give them a tad more mealworms and snails when adult depending on the weather, when dry or frozen some more, every day a bit though, and leave them when young as soon as possible the weather allowes in the yard. Even when it is only one hour that the temperature allowes it; so they can get some healthy nutrient themselves. Daily we spade a piece of yard and throw a bucket of water in it because they can get a lot of nutritient from the ground in the Netherlands.
But 10 months old.. It lookes like a vitamin B-thing..
Are they able to feed themselves in the yard? Like you often don't have to even feed them? Or is it a smaller Dutch garden; because then you might give some extra insects. What food do you use?
And offcourse;
HOOOOI! HOERA! EINDELIJK NOG EEN NEDERLANDER!
P.s. what an awesome vet do you have. I'm still looking for one that dares to treat ducks.
