Please help, my hen has a wound on her back from rooster claw, I have no way to get to a store until tomorrow.

Update: I ordered Lilac some vetericin hyrogel, nonstick gauze pads and vet wrap, and a saddle that should all get here tomorrow. I made saline, rinsed her wound, which is more of a tear but not bleeding, and applied some Neosporin and covered it with a bandaid---hoping that works okay. She has a pretty big bare patch with no feathers, so it's mostly stuck to her skin. I've got a soft fleece apron on her too.

I set her up in a wire dog kennel in the coop, which was okay until everyone else went to roost, then Lilac started panicking trying to get out (I've got a camera in the coop so I've been watching) so I let her out and she's much happier now and snoozing.

I plan to make enough saddles for all 14 of the hens, just in case. Wish I could get the rooster to control his urges.

She has a wound about the size of a quarter, on her back, where roosters left foot lands. Not a puncture I don't think but very raw and open, not bleeding. I've got a cage so she can be isolated.

I have on hand cornstarch, Neosporin, benzalkonium chloride towelettes, and large bandaids that I can cut the nonstick pad out of. I've got ace bandages, but nothing that sticks to itself like vet wrap.

No saline, but have a sealed bottle of purified water.

What can I do for now, and what should I get from tractor supply tomorrow?
