How is your hen doing?
Cefdinir is included in the class of cephlasporins which also includes cephalexin. Cephalexin is an excellent bird antibiotic for skin infections. However, my country internet signal is nearly nonexistent right now, and I couldn't find info when I googled "is cefdinir safe for birds". I would Not administer the antibiotic to your injured hen before confirming cefdinir is bird-safe, but if you will research a little further and deeper, it may very well be safe to use. Below are two links with general info about cefdinir and cephlasporins.

Here is a very long avian study I merely skimmed through, but if you scroll through the article to "antibiotic resistance in birds", you will see that cephalexin is listed as a first generation cephlasporin, while cefdinir is listed as a third generation cephlasporin. The fact cefdinir is listed in a bird antibiotics study is encouraging. If this were my hen, and knowing cefdinir was all I had available (since bird and fish antibiotics are no longer available otc), I would make it my mission to research and dig as deep as possible to learn whether or not cefdinir is bird-safe. I suspect it is, but please do your research and confirm. Good luck with your hen; I wish her speedy healing.
