DNA testing for breed in chickens

[Bird nut 2000]

I have a rooster that I'm unsure of how his parents were he is bigger then both of parents I think he is related too. But I did get a new hen and roo before he was incubated and hatched. The new roo was bigger than him but not the hen I want to know if the new ones were his parents or my older pare.

And am wondering if I can get his DNA tested to see how he is related to?

Both parent pares are mix is but of different breeds from each other.

Also how much would it cost to do to get a DNA test on him?
