I know white on that breeds a fault, which is why you don't see older. IRS at shows. However if you raised the bird from young and knew it started without the extra white then it would still be breeding stock worthy.

When breeding aggressively for SOP- how do you cull? Sell off excess as pets, euthanize (and how?)- thank you!To answer your question directly:
Color is a critical component to type in waterfowl, so you must worry about both.
A drake has much more influence because he will sire multiple hatchings from several different ducks. However, if you can get your hands on a super quality duck, you can manage your hatchings so her eggs are the ones you hatch for your next generation. A top quality duck is a real blessing to anyone who wants to produce top quality ducklings. However, I would purchase a quality drake to upgrade a pet flock, but would not purchase a quality duck and then breed her to a pet quality drake.
Automatic cull for me; Poor temperament. Any health issue. Even a hint of weak wing tendons (angel wing). Laying problems. Any deformity. The misfortune to be an excess male.
Add better bloodlines immediately. You can't start too soon. And cull, cull, cull.
Personal experience with breeding up waterfowl:
I have show quality Blue Swedish ducks., They are pretty decent, but could use some work. These are the best ducks I could find, so buying a better drake probably is not going to happen. The world is full of pet quality bib marked mutts and there are barely any show breeders of Swedish ducks. Stock simply does not exist. I will buy it if I find it, but so far, nothing.
I cull my birds and keep the best. I have forgiven some color faults. My birds are too narrow across the back, and my widest drake lacks the white wingtips. I want his broad back more than I want the white wingtips, so he stays and I hope he will broaden up my flock.
The rest of the birds all have their white wingtips, so I will hope there is no loss of that gene. I will cull to keep broader backed ducks with white wing tips.
It's a balancing act. If none of my birds had white wingtips except for one, who was too narrow in the body, I would keep him for his white wingtips and he would be used extensively white I got the correct wing color established. But again, I would be keeping the hatchlings with the broadest backs and also white wingtips.
Some faults are very difficult to get rid of. Mottled bibs is one of those in Swedish, so any bird with a mottled bib, or eye stripes, is out of the program. I can not afford to allow those genes to creep in. With those 2 issues, I don't have them and I don't care what great genes a bird has, I am not allowing those problems to get mixed into my gene pool.
I suggest that you do not concentrate on one trait at a time, but select the best over-all for each generation.
Oregon I have a question involving color. I know white on the plumage of a Black bird like a Cayuga is a big thing in the showing world. Would a Drake with any white on his plumage in breeds like that be a automatic cull for you? Is that something to hard to breed out?

Can they still be shown or will so many points be deducted it would be pointless to enter them?

I am interested in Silver Appleyard ducks. I am planning to get some from Holderread. Would this be good quality stock to start with? I've always heard his stock is great.
