Yes, but it is probably better to use plain neosporin along with something nasty tasting. It is also useful to provide alternative targets of their attentions, i.e., extra protein and fruit. High quality bird feed, hang up a peach in the coop, flock block/suet cake (if nothing else).
If any are bleeding a lot you should separate until the wounds scab over.
ed: Do you have a heat lamp running through the night? This can result in increased activity levels.
How many chooks do you have and how big is the coop? More irritable when crowded
We always leave the heat lamp on and this has never happend! Should I put neosporin and bag balm??? gah silly creatures!!! they have lots of room and we let them free range alot except they dont like the snow so it has been less...
Bag Balm and neosporin will work (pine tar will, 99% of the time, keep them from repeating), but to prevent this happening often get something that tastes bad - pine tar/masks injury (like blu-kote).
We keep a 15w incandescent in a securely fastened shop lamp fixture aimed up at the inside of the roof. This provides just enough light to see, but keeps them calm. It was -4°F here this morning and, though most don't want to come out (one BSL hen joined the turks outside), all are in good shape.
