A chicken tractor is a portable pen that is moved daily to new ground, and it moved it around both sides of the trees. They clean up bugs, scratch up the soil slightly and leave fertilizer behind. My husband makes a mineral mix which has all the trace minerals in it, along with the major calcium/phosphorus and potassium. Has 3 kinds of clays, kelp, azomite and lots of other stuff. Works miracles. We even sell it since so many friends wanted some after seeing our gardens.

I put minerals around all of them and built a small chicken tractor which was rotated under all three pear trees. I pruned off the dead or dying branches and what grew back was simply amazing. Much healthier trees and plenty of fruit. Fire blight did not recur until two years after I stopped doing the chicken tractors there and neglected putting out an annual application of minerals.

Those don't look like canker to me. It looks like the tree is just trying to heal over possibly from a damaged branch or where it was possibly pruned too far from the tree.
I would prune it right close to the trunk and I think it'll heal over nicely.
Best of luck!
