Hi, looking for any guidance with my sick chicken. She a 4 yr old buff. I’ve given her a warm bath, separated her from the others, and sprayed her vent with an anti-fungal and antibacterial. Shes not eating or drinking. I’m getting her to take some fluids with electrolytes from an eyedropper. She was totally fine in the yard foregoing with all the other chickens. Then the next day she was breathing heavy and putting herself in the corner of the coop or standing resting her head on a wine barrel.
