Clipped a chicken's wing a little to far

I was clipping our leghorn pullet's wing this morning and got a little carried away. I clipped one of her wings two nights ago (thinking that'd throw her off balance when attempting to fly) but it did not work. She still flew out of the enclosure last evening. We have been sighting bears and bobcats, so if she flew out at the wrong time, in the wrong place, she'd be no longer.............so I am trying to trim her wings AS MUCH as possible. But on one of her wings, the first primary flight feather I cut about 1 inch above her actual wing (like the part that grows all the flight feathers from it) and the remaining part of the feather had some blood in it after I cut. Should I apply betadine or cornstarch?
