Anaphylactic shock? Just gave injection!

Update: from husband

We'd been treating her after having an avian vet professor from Cornell look at her last week for suspected egg peritonitis, due to sick crop, due to a bad order of feed with some corn that wasn't crushed (causing crop and gizzard impactions in some of our birds - she was one). She very rapidly went off of water and food and became weak so we couldn't get much in the way of anything oral into her.

As a last ditch effort I administered the 1/4cc of Penicillin G Procaine using prescribed inter-muscular techniques and when I placed her on the ground she immediately went into shock and died. Quite correct, it's not something I'd care to ever repeat.

The necropsy confirmed egg peritonitis and some round worms (though we treated for round worms last week, she was too weak to safely receive a dose of ivermectin so I wasn't very surprised to find them) and I dissected the breast at the injection site and found the small pocket of liquid penicillin right beneath the first few layers of muscle, with no blood vessels visible.

We really appreciate everyone jumping to offer advice, thanks for trying to lend a hand.

You're very brave chicken owners--sorry for your loss.

Ivermectin has really lost it's effectiveness as a wormer for the last few years, even though many online sources about worming still recommend it. The best 2 wormers on the market are Valbazen (albendazole) and SafeGuard liquid goat wormer or equine paste (fenbendazole.) These are given undiluted 1/2 ml for most chickens, 1/4 ml for bantams. Worm Out Gel is a newer mix of oxfendazole and praziquantel that can be given in the water over 2 days.

question please eggsessive. has ivermectin lost its effectiveness because its over used in the chickens or the worms have built immunity ? i mean if MY chickens have never had it before would it work good on them? if you know please?

Dawg53 and others have said that it is because it was overused so much to treat mites for years, that worms have built up resistance to it.
