New to duck care and raising, need lots of help!

Hello! So, i have been searching all day on this website and on others about what to feed ducklings. I am going to get some duckling in a few days, or a week, and im trying to prepare for them. Im am so confused on what to feed my ducklings when i get them. Is it ok for ducklings to eat chick starter? What can they eat? I live near an Olsens Grain and i have seen that they have all kinds of bird feed, but dont have duck feed, starter or adult feed. Is there any kind of safe alternative to duck starter/adult duck feed? As you might tell, im very new to raising ducks. I have many questions but i keep finding tone of mixed opinions on them. Also when they grow up, whats the best to feed them then? Does it matter with different breeds, or even mixed breeds? I just need some advice, im so conflicted on everything.

Secondly, i have two dogs who are barkers. My coop for the ducks is in the back yard, but thats also where my dogs go, for we dont have a fenced in front yard. Is this a big problem? I dont think they will be able to get into the coop, but if they bark and pee/poo, will that scare or agitate then ducklings?

Thirdly, the ducks that im will be wanting/getting are one and two weeks old. Will they be able to stay in the coop or will i need to bring them inside?

Im sorry i have so many question, im just really new and worried i could hurt or kill these little ducks. Thank you so much or any advice!!

What breed or dogs do you have?

Purina flock raiser, nature wise all flock and blue seal home fresh multi flock are all one stage feeds that ducks can eat. Game bird and turkey comes in 3 stages, starter, grower and finisher/maintain. Ducks must all ways have water when being feed! If not they can choke on the dry feed.

How big is the enclosure? How many ducklings are you getting?

At 6 weeks they can start living outside.

I have two dogs, one is an elderly blue tick hound and the other is a one year old miniature pinscher/pug mix. They both bark and whine very loudly, and the coop is right by the neighbors fence, who also own two loud barking dogs. Im just worried that the ducks could be frightened or agitated...

The enclosure is about 5x5 for the boxing areas and the fenced area is 4x5 and i'm getting two ducklings. Its quite a small pen, but originally was a chicken coop. We are planning on doing repairs though because its in a quite awful state. Thank you for you're help!

You may want to sprinkle a tablespoon of brewer's yeast (not baking yeast) on their food once a day for their first ten weeks - it supplies extra B vitamins.

And please keep us updated! This is a very helpful group.
