so I recently bought 2 adorable Rhode Island reds last week from a hatchery. One of the unfortunetly died last week and now the other one seems to be declining in health. She has a small eye infection that I've been putting vetrx in. I'm putting probiotics and electrolytes in her water and feeding her chick feed with amprollium. Should I start her on full strength Corid tonight? She also recently lost a patch of feathers on one of her wings and I am just very worried she isn't going to make it..
