I think chickens are allergic to the -ine medicines like the pain killer version of Neosporin and Bactine.
Some wounds you want to keep moist so a petroleum jelly based medicine like Neosporin is a good idea, but I think blisters make their own moisture (the clear liquid) so you want to allow them to dry out.
