The idea that God is radically free and that there are no real relations has further implications, I think (I don't know that Ockham would agree with what follows, so...)
God is radically free in the sense that God did not have to use a particular kind of order in creating. Creatures are distinct entities. According to Ockham, I cannot infer, a priori, the cause of an effect. I can infer that an entity has a cause, but there is no "real relation" by which I can deductively know anything about the cause itself. The only way I can know the cause is by observation.
This goes back to God's freedom. God was not necessitated in such a way that God could only create the present order. The present "order" is simply a collection of relations that have no real entity. So, if that's the case, notions such as "kind" go out the window. At least, there is no essence that necessitates one kind generated the same kind. There are only contingent collections of entities. God very well could have created such an order that ducks gave birth to chickens, who in turn gave birth to elephants. And, if God had done that, it would be the present order and would make perfect sense.
I think it appears obvious that God could have created a world that had a different order (different physics?), but when you try to think of specifics it gets wonky. But, for Ockham, that oddness is simply the result of this being the only contingent world we know by experience.
