Hello, I have had issues for the last 2 weeks with a 3ish week old sapphire gem. I brought her (?) home from the local farm store & discovered a bald, SMELLY, dirty, crusted rear end. She seems to be leaking clear-ish fluid that dries white. A few days ago, I noticed that one of her knees was beginning to swell. She still walks on it & did not witness an ninjury happen. I clean her up 3x daily & the discharge just continues. This is not pasty butt! It looks like vent gleet but 7 days of monistat orally & IN the vent has not helped. 
I've had a hard time finding anything online & this is my last resort. I need to figure out what's going on, because I can't clean a full grown hen 3x daily. What's she going through CAN'T be comfortable.
Her & 7 other thriving chicks are in a fenced in kiddie pool in my spare bedroom with a red brooder light. Feeding kalmbach 18% chick starter. Offering chick grit, plain water & ACV water. Pine shavings for bedding.
She eats & drinks & does chicken things. She does spend a little more time under the light than the others, but she's been half bald underneath (but feathers are growing back!) Poop looks normal. Although sometimes she strains to poo & squeaks while doing so. Her growth rate may be a little stunted, but I don't have another gem of the same age to compare her to.
What I've done to treat:
Kept vent clean
Monistat treatment (no help)
Probiotics
Electrolytes
Prep H for vent swelling
ACV in water
Zyfend backyard chicken 2 days (per the farm store lady)
Blukote
I'm not sure what else I can try. My local vets either don't treat birds or have no available appointments.
Sorry for the long post & thanks in advance!
