I was breeding Pidoves to try some IV breeding.
I had a 2 IV male with attack and speed and a female pidove with Speed IVs
The male was holding a destiny knot and female was holding a Power Anklet.
I got a female pidove with 1 IV in Speed.
Have I done something wrong ?
Destiny Knot IV breeding only works in X/Y so if you are using it in previous gens then it won't work.
But if you ARE using the Destiny Knot in X/Y it only passes 5IVs from either parent so it doesn't always transfer the IVs you want, so you have to rely on chance.
As far as I can tell, you did nothing wrong.
The destiny knot transfers 5 random IVs from the parents to the offspring, I guess it was just bad luck this time.
Hope I helped.
