Just wondering the likelihood of this. I have blue swedishes and french muscovys, with one drake of each. I had a muscovy mama sitting on a mixed clutch of eggs, and two hatched earlier (normal time) and the rest were definitely muscovys and took 35+ days. The whole time I thought I had an early muscovy duckling and a blue swedish, based off of appearance. I've bred several rounds from my 1/2 pekin 1/2 blue swedish drake (looks full blue swedish in coloring, but has some pekin-ish shape) to my full blue swedish gals. All offspring has been classic blue black and splash swedish in appearance, even though they technically have 1/4 pekin. Then I get this guy who is HUGE and grew super fast, but is not looking like my french muscovys at all except in size. He looks exactly like a full pekin. So I can only assume that this is from my blue swedish parents and that 1/4 pekin gene went full pekin in appearance for this duckling? I was pretty confused for a long time because he didn't look like my french muscovys except the full white color and giant size. What are your thoughts? I'll post a picture in a minute when I go out to feed everyone!

Could it be Silver? The duck in my avatar is a silver. It results from two blue alleles. That would make your duck female as the males are usually white and grey. The white like a Pekin requires two recessive alleles so unless your Blue Swedish isn’t really a Blue Swedish, that seems unlikely. I do not know Muscovy genetics at all so just a guess.
 
Just looked it up and white in Muscovies is incompletely dominant. So, could your baby be a mule duck with a white Muscovy mother and the white recessive allele from the Pekin half of your drake?

I don't believe it is from the muscovy mom as they were seperated (mama muscovy and muscovy drake from the swedishes) and all the other babies she hatched were definitely muscovy. I just mixed up which eggs she was laying on and didn't keep track of them after she started brooding. She had 7 muscovy and 2 swedish eggs under her that hatched at different times obviously.

My blue swedish is half pekin half swedish. 8 week old in question definitely isn't muscovy based off of development and he hatched at 29 days instead of 35+. I just assumed early muscovy because he was a white baby lol! The others look like propery muscovys. Already getting pink and red above their bills and have black spots on their heads like the parents.
