No I don't add poultry conditioner to their feed I don't even know what that is.
I feed them: scratch mix, corn, breed, a lot of green food plus they are free range at the moment.
I have three pairs of cayuga ducks and I also have 19 ducklings from them but the duckling have a bit of yellow fluff on there chest does this mean they are cross-breds?
Here is my cayugas.
