fruit trees buddgin early

Can I still prune them during the early budding stages?  Should I wait for the next cold spell and then prune or wait till summer?

How much pruning do they need? What shape and health are the trees in? How old are the trees? What are your goals for this pruning cycle, and how much previous pruning have they had? How much pruning needs to be done over all? What types of fruit trees, scion varieties and rootstocks are they if known? What stage of budding are they? All these things can determine what type of pruning, how much, and when is ok to prune. You can definitely do deadwood, and potentially redundant crowded crossing branches, as those are things the tree typically won't miss at any point. I would also advocate that restoration or restructuring be done over several dormant seasons, keeping the overall prunings not to exceed 20% per year.

My Asian Pears are all healthy and about 7 to 8 years old.  A lot of upward sprouts.  They have never produced anything more than one or two fruits if at all.  SOme are starting to leaf but others still have a tight bud.
My Pluots/Plums are starting to leaf and are only a couple years old. One has flowers.
