Could they be sexlink?

[newchickmom09]

My newly hatched ducklings all came out looking like either there mamma or dad. I was wondering if the ducklings could be sexed using there colors since there are brown ones and black ones. Cocoa the mom was brown as a duckling and Ebony the dad was black as a duckling. I normaly wouldn't care and just wait and see until they get older but tomorrow 7 out of the 9 ducklings are going to there new home. I am hoping

to keep two females out of the bunch. I am not comfortable vent sexing so for me it is just a waiting game. I just thought maybe there might be a chance they could be sexlinked. I don't know how genetics and color work in waterfowl and trying to use a color caculator I found just came out with everyone being black.

Or is this just not how this kind of thing works? The family I am giving them to said if I end up with males then we can switch but it would be nice to try and get it right the first time.

Here are pics of Cocoa (brown female) and Ebony (black male) as ducklings:

Here they are grown up:

Now here are there new ducklings: the ducklings look just like mom and dad

Sometimes offspring can be sex linked, but aside from Holderread's explanation with an example of chocolate and black runners in Storey's Guide, I am clueless.

No, unfortunately, that is not a sex-linked mating. The reverse would have been, for example brown drake on black duck.
