Some of My Peaches Are Leaking Sap

Question

What’s wrong with them? I have three O’henry peach trees. They seem to be healthy except one has almost no peaches. The other two have many peaches that are not developing and some that are developing. Out of the good ones about half have the sap oozing from the seam. The trees are about five years old. Last year all three trees produced massive amounts of excellent fruit.
