i looked up wound care because it was christmas eve eve, and we have NO vets that treat chickens
All vets treat wounds on any animal, even though a lot of vets don't have much knowledge about birds of any sort. This bird needs to be seen by a vet. The vet can also give you something to give the bird for the pain, which she is undoubtedly suffering.
I know about everyone here on this forum is all about "saving" every animal, and I understand... it's hard to let them go.
Agreed, 100%. It's hard to let them go, but there are some cases where it is far kinder to do so. Knowing the difference is hugely important, and a lot of unnecessary suffering has been caused in this world by people playing amateur vet, and prolonging a life that should have been painlessly ended long before.
This may be one case in point. The bird may or may not survive, but it has already, and will continue to, suffer a lot, no matter what the result ends up being.
Growing up in the country, we had hundreds, probably thousands, of animals that we had to make choices about over the years....our own pets, plus sheep, cattle, horses and so on....and you need to make the right choice for the animal, not for yourself.
If you want to keep trying to treat her, she needs to be seen by a vet to get treatment for pain, and advice on whether or not she may be saveable.
Sorry if that sounds harsh, and I'm sorry that it happened at all, especially on Christmas, but I prefer to call things as I see them.
Best of luck, and I hope you and your family and hen have a merry Christmas.
