I have an oak!

I just discovered a volunteer oak in my garden! It’s growing in an old raised plant bed I had which would be the perfect spot for an oak except I have chicken wire underneath to stop the gophers coming from underneath. I am afraid that if I let it be the roots will get strangled by this and it will kill tree. However if I dig it up to transplant it I will kill it as well. Hard to know the right thing to do!?
