Thank you, @DwayneNLiz . No apologies necessary! Yes, this thread is all Mrs. Pickles.
Over the past 6 months, for one thing or another she had had:
* shots of baytril given by the vet (antibiotic)
* shots of meloxicam given by the vet (pain & swelling)
* soluble tylosin (antibiotic)
* sulfamethoxazole/trimethoprim (antibiotic)
* meloxicam (pain & swelling)
* valbazen (she had worms)
* ivermectin (she had lice)
* tobramycin ophthalmic drops (eye infection)
She has been checked for eye worms and thankfully we haven't dealt with those.
The month she was entirely well, she had lice then worms. She when she gets sick, she is quickly back to her normal self.
It seems like a ton of antibiotics, but this is a 6-month period of being sick.
Right now, she's doing normal chicken things again. In our experience, when the lesions become really nasty looking, she starts feeling better. Every time I've decided it's time to have her put to sleep, she is back to happy chicken things. I've gone as far as getting the carrier down and walking outside to find her dustbathing then running around.
She filed her chipped beak down to normal the day after I posted the picture with the overgrown beak & chip.
