BYC ers seem to recommend antibiotic ointment Without pain medicine (lidocaine, etc) as a good, general purpose treatment for wounds. I hope your hen is safe from her flockmates until she is fully recovered.
I'm not very informed about sick chicks, however, my vet told me that "the solution to pollution is dilution" in normal terms, that meant that lots of fluids would/could dilute poisons. Will the chick take drops of water with vitamins in it? Wish I could help more, I'm so sorry for your loss.
Three feet high, gives the girls an extra roost to enjoy, still tall enough for me to access but short enough that I can still service the upstairs. The result is more square footage with a smaller footprint in my small garden.
This is so frustrating, give them everything you think
they could possibly need and they still eat eggs! I might
get a roll out nest arrangement but don't have room.
What is working for me is collecting eggs two or more
times a day, I always get a kick out of getting there first...
Never...
