Call Duck Breeding

The first pair that are both blue fawn will produce 25% grey, 25% pastel, and 50% blue fawn.

The trio that are all grey will produce only greys. Blue is incompletely dominant; the grey drake being from a blue fawn mating doesn't mean he has blue genes. If he did, he'd be blue fawn.

Pair two of the whites, all offspring will be white, and half will be crested.
What creates the pastels since there is just blue fawn and grey for my pairs parents?

Since the two blue fawns will be breeding together, 25% of their offspring would get a copy of the blue dilution genes from both of the parents. Blue is incompletely dominant - one copy of blue, when added to a grey duck, makes blue fawn, which is what the parents in this pair are. Two copies makes pastel. Since each blue fawn has a copy, 25% of the ducklings will be getting a copy from each parent, meaning they will have two copies, and the result of that is pastel :)

This chart is chickens, but blue breeds the same in ducks. Basically, in terms of equivalence to this chart, grey is 'black', blue fawn is 'blue', and pastel is 'splash'.

Were the ducks not on the mallard (grey) base, then they really would be black, blue, and silver (splash) :)

Here's an article I wrote on duck color genetics that explains it more in depth:

Oops you are right! I was confused with the first one. I thought the OP said one parent was grey and the other blue fawn. I didn't realize they were both blue fawn. Sorry, @Old McRonald
You will actually get 25 percent grey 50 percent blue fawn and 25 percent pastel.

Pastel is the duck equivalent of splash in chickens.
 
Thanks but having 3 drakes already I’d have to keep that little one inside! Just good he’s A he because female crested can be injured with breeding.
That's what I've heard so that is why I don't want to raise more of them. He's a nice little duck but he will be getting rehomed for sure. Going to replace him with a show quality drake.

No problem! I added the part about their parents just in case it could have been a factor.

I love this chart, it tells me at a glance what I could get from different crosses. I am kind of a purist so I will only be keeping them together in the groups I mentioned. Very good article also, I won't be giving any lectures on genotypes and alleles anytime soon but it does help to understand the genetics of it all.
