Apple seeds poisonous to ducks???

[BigWeenMachine]

I made a smoothie for my ducks and turkeys with one small apple and 2 small pears as well as a grapefruit and orange. Is that enough seeds to kill them??? It is all blended up now so I can't pick out the seeds. However, I did pull most of the seeds out of each pear before I blended it.

Apple seeds are toxic but I'm not sure how much is needed. Also they aren't suppose to have citrus either
