Sooooo Eggcited!!!!!!!!

Congrats!
I would get a second duck. They get a bit lonely when they are all alone.
I had Cayugas. They are so very gentle and sweet. Not to mention how nice
they look in the sun.

Tips:
They like to have a friend.
I would get 2 hens not a hen and a drake. He will stress her out if she is the only she.
They can have a shallow pool when they are only a few days old. Make sure you limit the time
in the pool until they are well feathered and can get out regularly on their own.
MAKE SURE they can get out of the water on their own. Make a ramp of stones that they cannot dislodge. If not they can drown.
All Flock is a good feed for ducks. You can feed layer feed if you are feeding hens once they are
of laying age.
Mine never wanted to go in the barn and had to be herded in at night to keep them safe.
Foxes, raccoons, skunks and most other critters think ducks are even tastier than chickens.
You can't beat a good fence.
Even if they do not want to go in at night MAKE THEM.

I am glad you chose the Cayuga. They are wonderful pets and they are not loud.

 

Have fun with your new babies. I am so glad your dad said yes!
