My 5 month-old dark brahma pullet, Princess, has been sick for weeks now - I've tried everything but am at a loss.
She's declining rapidly and I fear for the worst
Symptoms: itchy, bubbly eyes, incessant head shaking and scratching - swollen eyelids, feathers scratched off around her eyes.
I've isolated her twice, she's had two rounds of Tylan-50 (5 days each time), a round of Tetracycline, she's been dewormed in December with Piperazine and last week with Ivermectin.
No lice, mites or any other parasites. Poops normal.
Feathers around neck thinning out - scratching? being attacked by others? I don't know.
Up until 3 days ago she seemed to be eating well but now she's lethargic, poofed up in a corner with her eyes closed between rounds of scratching. She feels lighter, like she's not eating much.
The breeder told me to give her an aspirin with 1 cc of Tempra, then 1 cc of Tempra a day for 3 days after that. Today was her 3rd dose of Tempra. He thinks it's a cold but since giving the meds she's gotten worse.
No other chickens in the coop have this, they are all healthy and thriving -
Please help!!!
